dm: pass gfp_mask to alloc_rq_tio

This patch adds the gfp_mask argument to alloc_rq_tio().
No functional change.

This patch is a preparation for a later patch in this series which needs to
allocate tio (for barrier I/O) with different allocation flag (GFP_NOIO) from
the one in the normal I/O code path.
