selinux: stop flooding the log buffer

Browse source 
The avc allocations are marked with GFP_NOWAIT and thus
considered to be non-fatal allocations. This also makes
these allocations easy to fail thus filling the log buffer
with page allocation failure messages. There are no known
cases of these messages being of any importance for
debugging. Disable them.
