dm mpath: fix bio-based multipath queue_if_no_path handling
Commit ca5beb76 ("dm mpath: micro-optimize the hot path relative to
MPATHF_QUEUE_IF_NO_PATH") caused bio-based DM-multipath to fail mptest's
"test_02_sdev_delete".
Restoring the logic that existed prior to commit ca5beb76 fixes this
bio-based DM-multipath regression. Also verified all mptest tests pass
with request-based DM-multipath.
This commit effectively reverts commit ca5beb76 -- but it does so
without reintroducing the need to take the m->lock spinlock in
must_push_back_{rq,bio}.
Fixes: ca5beb76 ("dm mpath: micro-optimize the hot path relative to MPATHF_QUEUE_IF_NO_PATH")
