migration/multifd: Fix error message in multifd_recv_initial_packet()

In multifd_recv_initial_packet(), if MultiFDInit_t->id is greater than
the configured number of multifd channels, an irrelevant error message
about multifd version is printed.

Change the error message to a relevant one about the channel id.
