io_uring: switch struct io_ring_ctx internal bitfields to flags

Browse Source 
Bitfields cannot be set and checked atomically, and this makes it more
clear that these are indeed in shared storage and must be checked and
set in a sane fashion. This is in preparation for annotating a few of
the known racy, but harmless, flags checking.

No intended functional changes in this patch.
