block/io_uring: pass in issue_flags for uring_cmd task_work handling

commit 9d2789ac9d60c049d26ef6d3005d9c94c5a559e9 upstream.

io_uring_cmd_done() currently assumes that the uring_lock is held
when invoked, and while it generally is, this is not guaranteed.
Pass in the issue_flags associated with it, so that we have
IO_URING_F_UNLOCKED available to be able to lock the CQ ring
appropriately when completing events.
