[PATCH v2 5/9] staging: vchiq_arm: pass vchiq instance to 'vchiq_get_client_id'

[Adrien Thierry]

In order to remove the 'vchiq_states' global array, we need to pass the
vchiq_instance reference to the 'handle_to_service' function, as well as
to all functions that call 'handle_to_service'. This will allow
accessing the vchiq state through the vchiq instance instead of through
the global array.

'handle_to_service' is called by 'vchiq_get_client_id'. Therefore, pass
the vchiq instance reference to it.
