Make gem_mmap__{cpu,gtt,wc}() assert on failure

Browse Source 
Rename the current gem_mmap__{cpu,gtt,wc}() functions into
__gem_mmap__{cpu,gtt,wc}(), and add back wrappers with the original name
that assert that the pointer is valid. Most callers will expect a valid
pointer and shouldn't have to bother with failures.

To avoid changing anything (yet), sed 's/gem_mmap__/__gem_mmap__/g'
over the entire codebase.
