Well, currently IPC depends on hal-msg.h which defines max allowed service ID
and using something bigger is a code bug. We could have make IPC independent
of hal-msg.h and just verify registered ID in runtime but that would add extra
code for each caller with no profit as IDs are fixed anyway.
That test fix is invalid as we actually want to test if IPC handles out-of-
bound service ID correctly (when receiving register command).
And I'm not sure why this actually was causing any problems since that test is
not registering handlers for out-of-bound service ID, just sends ipc message
with such ID.
(BTW I think we should pass max service id on ipc_init, as currently audio ipc
is using max service id from bt ipc)
