When migrating a range of system memory to device private memory, some of the pages in the address range may not be migrating. In this case, the non migrating pages won't have a new GPU MMU entry to store but the nvif_object_ioctl() NVIF_VMM_V0_PFNMAP method doesn't check the input and stores a bad valid GPU page table entry. Fix this by skipping the invalid input PTEs when updating the GPU page tables.
