drm/amdkfd: Fix reserved SDMA queues handling
This patch fixes a regression caused by a bad merge where
the handling of reserved SDMA queues was accidentally removed.
With the fix, the reserved SDMA queues are again correctly
marked as unavailable for allocation.
Fixes: a805889a1531 ("drm/amdkfd: Update SDMA queue management for GFX9.4.3")
