Revert "io_uring/rw: drop -EOPNOTSUPP check in __io_complete_rw_common()"
Commit 927069c4ac2cd1a37efa468596fb5b8f86db9df0 upstream.
This reverts commit 90bfb28d5fa8127a113a140c9791ea0b40ab156a.
Kevin reports that this commit causes an issue for him with LVM
snapshots, most likely because of turning off NOWAIT support while a
snapshot is being created. This makes -EOPNOTSUPP bubble back through
the completion handler, where io_uring read/write handling should just
retry it.
Reinstate the previous check removed by the referenced commit.
