Subject: [PATCH] block: make sure ->nr_integrity_segments is cloned in
blk_rq_prep_clone

Make sure ->nr_integrity_segments is cloned in blk_rq_prep_clone(), otherwise requests cloned by device-mapper multipath will not have the proper nr_integrity_segments values set, then BUG() is hit from sg_alloc_table_chained().
