genetlink: export genl_unregister_mc_group()
Add an EXPORT_SYMBOL() to genl_unregister_mc_group(), to allow unregistering groups on the run. EXPORT_SYMBOL_GPL() is not used as the rest of the functions exported by this module (eg: genl_register_mc_group) are also not _GPL(). Cleanup is currently done when unregistering a family, but there is no way to unregister a single multicast group due to that function not being exported. Seems to be a mistake as it is documented as for external consumption. This is needed by the WiMAX stack to be able to cleanup unused mc groups.
