staging: vc04_services: handle kzalloc failure
[ Upstream commit a5112277872a56017b777770e2fd4324d4a6c866 ]
The kzalloc here was being used without checking the return - if the
kzalloc fails return VCHIQ_ERROR. The call-site of
vchiq_platform_init_state() vchiq_init_state() was not responding
to an allocation failure so checks for != VCHIQ_SUCCESS
and pass VCHIQ_ERROR up to vchiq_platform_init() which then
will fail with -EINVAL.
