dm mpath: factor out SCSI vs NVMe path selection
Trying to do both SCSI and NVMe bio-based handling with branching in the same common code has proven too tedious on a code maintenance level. In addition it slightly hurts IO performance. Fix this by factoring out __map_bio() and __map_bio_nvme(). Signed-off-by: Mike Snitzer <snitzer@redhat.com>
