Assign result of `register_dissector(..., func, proto)` to FOO_handle and remove `FOO_handle = create_dissector_handle(func, proto)`. Found by looking for files named packet-FOO.c having the above create_dissector_handle pattern. Some files (with different dissect routines for the two functions) remain unchanged.
