Andrey Grodzovsky 3273d3bfe5 drm/amd/display: Fix race.
Problem :
A race between two adjecent page flips makes the earlier one
to release an alocated frame buffer for the subsequent one -
since there are 2 frambuffer swapped back and forth between flips,
the 'new' fb of the later flip is actually the 'previous' fb for the earlier flip.
Fix:
Don't set fb->address = 0 in cleanup hook, this is unnecessery and
erases the newly cached adress that was set in prepare_fb of the second
flip.
