dm: fix bio_set allocation
The use of bioset_init_from_src mean that the pre-allocated pools weren't
used for anything except parameter passing, and the integrity pool
creation got completely lost for the actual live mapped_device. Fix that
by assigning the actual preallocated dm_md_mempools to the mapped_device
and using that for I/O instead of creating new mempools.
Fixes: 2a2a4c510b76 ("dm: use bioset_init_from_src() to copy bio_set")
