md: set md-specific flags for all queue limits

The md driver wants to enforce a number of flags for all devices, even
when not inheriting them from the underlying devices.  To make sure these
flags survive the queue_limits_set calls that md uses to update the
queue limits without deriving them form the previous limits add a new
md_init_stacking_limits helper that calls blk_set_stacking_limits and sets
these flags.
