md: raid-1/10: fix RW bits manipulation
Recently Jens has changed bio_rw_flagged() logic by following
commit 1f98a13f623e0ef666690a18c1250335fc6d7ef1. Now it returns
bool instead of int. This broke raid1/raid10 RW bits manipulation logic.
One of visible result is BUG_ON triggering due to empty barrier
here scsi_lib.c:1108 scsi_setup_fs_cmnd()
