nvme-rdma: use nr_phys_segments when map rq to sgl
Use blk_rq_nr_phys_segments() instead of blk_rq_payload_bytes() to check
if a command contains data to be mapped. This fixes the case where
a struct request contains LBAs, but it has no payload, such as
Write Zeroes support.
Fixes: 6e02318eaea5 ("nvme: add support for the Write Zeroes command")
