staging: vc04_services: Unsplit user-visible strings

Commit 5ced5a899b405e09cc681b8a1a449815b66744c7 upstream.

This was found using checkpatch.pl's SPLIT_STRING warning. While joining
these strings makes for long lines, the kernel codebase consistently
does it this way to make user-visible strings easier to grep for.
