Benjamin Coddington 8afd47fecf tls: Fix tls_sw_sendmsg error handling 
JIRA: https://issues.redhat.com/browse/RHEL-60028

commit b341ca51d2679829d26a3f6a4aa9aee9abd94f92

    tls: Fix tls_sw_sendmsg error handling

    We've noticed that NFS can hang when using RPC over TLS on an unstable
    connection, and investigation shows that the RPC layer is stuck in a tight
    loop attempting to transmit, but forever getting -EBADMSG back from the
    underlying network.  The loop begins when tcp_sendmsg_locked() returns
    -EPIPE to tls_tx_records(), but that error is converted to -EBADMSG when
    calling the socket's error reporting handler.

    Instead of converting errors from tcp_sendmsg_locked(), let's pass them
    along in this path.  The RPC layer handles -EPIPE by reconnecting the
    transport, which prevents the endless attempts to transmit on a broken
    connection.
