wifi: lib80211: Constify struct lib80211_crypto_ops
Now that functions in lib80211 handle "const struct lib80211_crypto_ops",
some structure can be constified as well.
Constifying these structures moves some data to a read-only section, so
increase overall security.
Before:
text data bss dec hex filename
7273 604 16 7893 1ed5 net/wireless/lib80211.o
After:
text data bss dec hex filename
7429 444 16 7889 1ed1 net/wireless/lib80211.o

wifi: use struct_group to copy addresses
We sometimes copy all the addresses from the 802.11 header
for the AAD, which may cause complaints from fortify checks.
Use struct_group() to avoid the compiler warnings/errors.

Instead of open coding the CCM aead mode in the driver, and invoking
the AES block cipher block by block, use a ccm(aes) aead transform
which already encapsulates this functionality. This is a cleaner use
of the crypto API, and permits optimized implementations to be used,
which are typically much faster and deal more efficiently with the
SIMD register file, which usually needs to be preserved/restored in
order to use special AES instructions.

'cipher' algorithms (single block ciphers) are always synchronous, so
passing CRYPTO_ALG_ASYNC in the mask to crypto_alloc_cipher() has no
effect. Many users therefore already don't pass it, but some still do.
This inconsistency can cause confusion, especially since the way the
'mask' argument works is somewhat counterintuitive.
Thus, just remove the unneeded CRYPTO_ALG_ASYNC flags.
This patch shouldn't change any actual behavior.

This indicates a driver key selection issue, but even then there's
no point in printing it all the time, so ratelimit it. Also remove
the priv pointer from it -- people debugging will only have a single
device anyway and it's useless as anything but a cookie.

Don't use create_proc_read_entry() as that is deprecated, but rather use
proc_create_data() and seq_file instead.

Removing unnecessary messages saves code and text.
Site specific OOM messages are duplications of a generic MM
out of memory message and aren't really useful, so just
delete them.

When they were part of the now defunct ieee80211 component, these
messages were only visible when special debugging settings were enabled.
Let's mirror that with a new lib80211 debugging Kconfig option.

These bits are shared already between ipw2x00 and hostap, and could
probably be shared both more cleanly and with other drivers. This
commit simply relocates the code to lib80211 and adjusts the drivers
appropriately.
