[PATCH] sysfs: attribute_group: Respect is_visible_const() when changing owner

[Thomas Weißschuh]

The call to grp->is_visible in sysfs_group_attrs_change_owner() was
missed when support for is_visible_const() was added.

Check for both is_visible variants there too.

Currently there are no implementations of 'is_visible_const()' in the
tree, so this should not affect any code.
