Revert "block: end bio with BLK_STS_AGAIN in case of non-mq devs and REQ_NOWAIT"

This reverts commit 9eacc580e851dcd4473fec3b7646cdadca4e6088.

io_uring does do the right thing for this case, and we're still returning
-EAGAIN to userspace for the cases we don't support. Revert this change
to avoid doing endless spins of resubmits.
