generic: Test RWF_NOWAIT

Tests the RWF_NOWAIT flag so the I/O returns immediately with
-EAGAIN on a new file since it requires block allocation.

It creates a file, syncs it, and overwrites the file with
RWF_NOWAIT.  This should succeed.

Finally, read the contents to make sure the overwrite is successful.
