[GIT PULL] Smack additional patch for v5.11

[Casey Schaufler <casey@schaufler-ca.com>]

Hello Linus

Sorry for the 2nd pull request, but this is a fairly important fix
for the privilege handling of smackfs in the face of io_uring. The
novel use of kernel threads in io_uring invalidated an long standing
assumption regarding the privilege of kernel threads. The fix is
simple and safe. It was provided by Jens Axboe <axboe@kernel.dk>
and has been tested.
