Sorry, dm_destroy, not dm_table_destroy.  For dm_early_create it's
trivial as that calls both dm_table_destroy and dm_destroy in the error
path.  The normal table_load case is a separate ioctl, but if that
fails userspace needs to call the DM_DEV_REMOVE_CMD to cleanup
the state - similar to any other failure.
