dm-integrity: fix wrong fallthrough in integrity_bio_wait

Browse Source 
If dm_integrity_map_inline returned DM_MAPIO_KILL, the code would set
status BLK_STS_IOERR and then incorrectly fall through and submit the
bio. Luckily, dm_integrity_map_inline can't return DM_MAPIO_KILL at this
point, so the bug is just theoretical.
