msm: kgsl: fix accounting of memory mapped to userspace

Browse source 
The mapsize of kgsl_memdesc and gpumem_mapped of process are
incremented only in vmfault handler. But for cache modes
write through and write back, pages are inserted in kgsl_mmap.
So account for those mappings also in gpumem_mapped.
