staging: vchiq_arm: Drop unnecessary NULL check
Looking at the handling of service instance within the VCHIQ
driver shows that it's not possible that service_callback is
called with instance is a NULL pointer. So drop the unnecessary
NULL check and fix:
vchiq_arm.c:1109 service_callback() warn:
variable dereferenced before check 'instance' (see line 1091)
