dm: fix dm_wq_work() to only use __split_and_process_bio() if appropriate

Otherwise targets that don't support/expect IO splitting could resubmit
bios using code paths with unnecessary IO splitting complexity.

Depends-on: 3256ab3bb089 ("dm: avoid indirect call in __dm_make_request")
Fixes: b2e91778983a7 ("dm: optimize bio-based NVMe IO submission")
