drm/radeon: Don't flush the GART TLB if rdev->gart.ptr == NULL
commit 233709d2cd6bbaaeda0aeb8d11f6ca7f98563b39 upstream.
This can be the case when the GPU is powered off, e.g. via vgaswitcheroo
or runpm. When the GPU is powered up again, radeon_gart_table_vram_pin
flushes the TLB after setting rdev->gart.ptr to non-NULL.
Fixes panic on powering off R7xx GPUs.
