Konrad Dybcio 247849eeb3 drm/msm/a6xx: Avoid a nullptr dereference when speedbin setting fails ...

[ Upstream commit 46d4efcccc ]

Calling a6xx_destroy() before adreno_gpu_init() leads to a null pointer
dereference on:

msm_gpu_cleanup() : platform_set_drvdata(gpu->pdev, NULL);

as gpu->pdev is only assigned in:

a6xx_gpu_init()
|_ adreno_gpu_init
    |_ msm_gpu_init()

Instead of relying on handwavy null checks down the cleanup chain,
explicitly de-allocate the LLC data and free a6xx_gpu instead.
