Dave Airlie 6763a0aea6 nouveau/vmm: fix another SPT/LPT race 
We've had an unknown Turing issue for a while with page faults since
large pages and compression.

I've got a patch series that syncs all our L2 handling with ogkm and it
made this fault happen more.

After writing a bunch of debugging patches, I spotted an invalid LPT
entry where there should have been a valid one.

A 64K MAP succeeds on a range, but a subsequent SPT put drops SPT refs
across multiple ranges,

We shouldn't assume all ranges where SPTEs go away will have the same
sparse/invalid/valid state, just iterate over each instead and do the
right thing.
