Change mgr-&gt;available into mgr-&gt;used (invert the value).

Makes more sense to do it this way since we don't need the spinlock any
more to double check the handling.

v3 (chk): separated from the TEMPOARAY FLAG change.

<title>drm/amdgpu: user temporary GTT as bounce buffer</title>

<content type='text'>
Currently, we have a limitted GTT memory size and need a bounce buffer
when doing buffer migration between VRAM and SYSTEM domain.

The problem is under GTT memory pressure we can't do buffer migration
between VRAM and SYSTEM domain. But in some cases we really need that.
Eespecially when validating a VRAM backing store BO which resides in
SYSTEM domain.

v2: still account temporary GTT allocations
v3 (chk): revert to the simpler change for now

When we want to decouble resource management from buffer management we need to
be able to handle resources separately.

Add a resource pointer and rename bo-&gt;mem so that all code needs to
change to access the pointer instead.

No functional change.
