blk_rq_integrity_map_user() creates the ubuf iter with ITER_DEST for
write-direction operations and ITER_SOURCE for read-direction ones.
This is backwards; writes use the user buffer as a source for metadata
and reads use it as a destination. Switch to the rq_data_dir() helper,
which maps writes to ITER_SOURCE (WRITE) and reads to ITER_DEST(READ).
