[PATCH] drm/msm/a6xx: Fix build with !CONFIG_DEBUG_FS

[Yue Haibing]

From: YueHaibing <yuehaibing at huawei.com>

When building CONFIG_DEBUG_FS is not set
gcc warn this:

drivers/gpu/drm/msm/adreno/a6xx_gpu_state.c: In function a6xx_show:
drivers/gpu/drm/msm/adreno/a6xx_gpu_state.c:1124:2: error: implicit declaration of function adreno_show; did you mean adreno_dump? [-Werror=implicit-function-declaration]
  adreno_show(gpu, state, p);
  ^~~~~~~~~~~
