block: limit the Write Zeroes to manually writing zeroes fallback
Only fall back from hardware Write Zeroes failures when
blkdev_issue_write_zeroes returns -EOPNOTSUPP;
Note that blkdev_issue_write_zeroes turns any failure into -EOPNOTSUPP
when the write zeroes queue limit has been cleared to 0, so this still
catches all I/O errors where the driver detected missing support
for the hardware acceleration.
