dm raid: fix flush support
commit 0ca93de9b789e0eb05e103f0c04de72df13da73a upstream. Fix dm-raid flush support. Both md and dm have support for flush, but the dm-raid target forgot to set the flag to indicate that flushes should be passed on. (Important for data integrity e.g. with writeback cache enabled.)
