Do generic processing even for drivers which define .bdrv_check_perm

additional action on bdrv_check_perm, but don't want to reimplement
generic logic.

The patch doesn't change existing behaviour: the only driver that
implements bdrv_check_perm is file-posix, but it never has any
children.

Also, bdrv_set_perm() don't stop processing if driver has
.bdrv_set_perm handler as well.
