[Drbd-dev] [PATCH 1/7] cxlflash: query write_zeroes limit for zeroing

The write_same and write_zeroes limits for SCSI are effectively the
same, so the current code works just fine. But we plan to remove
REQ_OP_WRITE_SAME support, so switch to quering the write zeroes
limit for a zeroing WRITE SAME operation.
