Subject: [PATCH] gpu-compute: Fix flat scratch resource counters

Flat instructions may access memory locations in LDS (scratchpad) and
global (VRAM/framebuffer) and therefore increment both counters when
dispatched. Once the aperture is known, we decrement the counters of the
aperture that was *not* used. This is done incorrectly for scratch /
private flat instruction. Private memory is global and therefore local
memory counters should be decremented.

This commit fixes the counters by changing the global decrements to
local decrements.
