[PATCH] drm/amdgpu: increment queue when iterating on this variable.

[Nicolas Iooss]

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.
