staging: vc04_services: fix NULL pointer dereference on pointer 'service'
Currently, if pservice is null then service is set to NULL and immediately
afterwards service is dereferenced causing a null pointer dereference. Fix
this by bailing out early of the function with a null return.
Detected by CoverityScan, CID#1419681 ("Explicit null dereferenced")
