dm: move target request nr to dm_target_io
This patch moves target_request_nr from map_info to dm_target_io and makes it accessible with dm_bio_get_target_request_nr. This patch is a preparation for the next patch that removes map_info. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
