msm: kgsl: Prevent wrap around during user address mapping
When setting svm region during the gpuobj import ioctl call for a usermem
address, there is a possibility of a very large input size causing the
region's 64-bit end address to wrap around. This can cause the region
to incorrectly be considered valid, ultimately allowing a use after free
scenario. To prevent this, detect the occurrence of a wrap and reject the
import.
