xfs: check split_sectors validity before bio_split call

Browse source

Change the split_sectors check from !split_sectors to split_sectors <= 0
to make the error handling explicit. While bio_split_rw_at() cannot return
a negative error code for the current GC I/O path (GC I/O doesn't use
REQ_ATOMIC/REQ_NOWAIT flags and has proper alignment), making the check
explicit improves code clarity and makes the intent clear.

This also makes the code more robust for future maintenance if different
I/O patterns are introduced.
