GPU retry vm fault on unregistered address, new range is created to recover the retry vm fault. Instead of setting new range perferred_loc to GPU, add GPU to new range access_bitmap, to be able to update GPU page table after new range migrate to VRAM. The new range preferred_loc is default value KFD_IOCTL_SVM_LOCATION_UNDEFINED.
Correct one typo.
