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().
Fixes: b0fd271d5fba ("block: add request clone interface (v2)")
