svc: Add missing address range sanitizing checks to MapMemory/UnmapMemory

Browse Source 
This adds the missing address range checking that the service functions
do before attempting to map or unmap memory. Given that both service
functions perform the same set of checks in the same order, we can wrap
these into a function and just call it from both functions, which
deduplicates a little bit of code.
