The debugfs_create_blob() function has been used to create read-only binary
blobs in debugfs. The function filters out permissions, other than S_IRUSR,
S_IRGRP and S_IROTH, provided while creating the blobs.
The very behavior though is being changed through previous patch in the
series (fs: debugfs: Add write functionality to debugfs blobs) which makes
the binary blobs writable by owners. Thus, all permissions provided while
creating the blobs, except S_IRUSR,S_IWUSR, S_IRGRP, S_IROTH, will be
filtered by debugfs_create_blob().
As such, rectify the permissions of panicinfo file since the S_IFREG flag
was anyways being filtered out by debugfs_create_blob(). Moreover, the
very flag will always be set be set for the panicinfo file through
__debugfs_create_file().
