drm/amdgpu: increment queue when iterating on this variable.
gfx_v7_0_print_status contains a for loop on variable queue which does
not update this variable between each iteration. This is bug is
reported by clang while building allmodconfig LLVMLinux on x86_64:
drivers/gpu/drm/amd/amdgpu/gfx_v7_0.c:5126:19: error: variable
'queue' used in loop condition not modified in loop body
[-Werror,-Wloop-analysis]
for (queue = 0; queue < 8; i++) {
^~~~~
Fix this by incrementing variable queue instead of i in this loop.
