Revert "Merge branch 'loop-aio-nowait' into for-6.19/block"

This reverts commit f43fdeb9a368a5ff56b088b46edc245bd4b52cde, reversing
changes made to 2c6d792d4b7676e2b340df05425330452fee1f40.

There are concerns that doing inline submits can cause excessive
stack usage, particularly when going back into the filesystem. Revert
the loop dio nowait change for now.
