drm/radeon: partially revert "fix VM_CONTEXT*_PAGE_TABLE_END_ADDR handling"
commit 7c0411d2fabc2e2702c9871ffb603e251158b317 upstream.
We have that bug for years and some users report side effects when fixing it on older hardware.
So revert it for VM_CONTEXT0_PAGE_TABLE_END_ADDR, but keep it for VM 1-15.
