anv: leave the top 4Gb of the high heap VMA unused
In 628c9ca9 I forgot to apply the same -4Gb of the high address of the high heap VMA. This was previously computed in the HIGH_HEAP_MAX_ADDRESS. Many thanks to James for pointing this out. Signed-off-by:Lionel Landwerlin <lionel.g.landwerlin@intel.com> Reported-by:
