Log Message:
Don't map the GEM uvm_aobj copy-on-write -- what was I thinking?

Do transfer the GEM object reference to the uvm_aobj reference --
these are not the same thing.  (There's another uvm object whose
references are the same thing as the GEM object references, but
that's not the uao.)

With these changes, it looks like the GPU is no longer trying to draw
graphics all over kernel data structures.  Wish I had that month of
debugging back!
