Mandate ctx locking for task_work. Then, remove aux CQE caches mostly
used by multishot requests and post them directly into the CQ.
It's leaving some of the pre existing issue_flags and state conversion
non conformant chunks, which will need to clean up later.
v3: pass IO_URING_F_COMPLETE_DEFER to the cmd cancellation path
drop patch moving request cancellation list removal to tw
drop all other ublk changes
v2: Add Patch 3, which fixes deadlock due to nested locking
introduced in v1
Remove a fix, which was taken separately
Pile up more cleanups (Patches 12-14)
