[PATCH] md: call bitmap_daemon_work regularly

bitmap_daemon_work clears bits in the bitmap for blocks that haven't been
written to for a while.  It needs to be called regularly to make sure the
bitmap doesn't endup full of ones ....  but it wasn't.

So call it from the increasingly-inaptly-named md_check_recovery
