[PATCH 31/40] Replace virStringListLength where actual lenght is not needed

[Peter Krempa <pkrempa@xxxxxxxxxx>]

Some callers don't need to know the actual lenght of the list but only
care whether the required element is present or the list is non-empty.
Don't calculate the list length in those cases.
