You're correct that this is indeed needed.  However your solution
makes some assumptions about how the target is going to use the
device.  eg. you do the wrong thing for snapshot exception stores, or
mirror logs.  I think the correct solution would be to add some
utility functions to dm-table.c in order to make it easy for the
targets constructors themselves to do the checking.
