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.)
