drm/amdgpu/mes: Fix an error handling path in amdgpu_mes_self_test()

[PATCH] drm/amdgpu/mes: Fix an error handling path in amdgpu_mes_self_test()

Posted by Jianglei Nie 3 years, 9 months ago

if amdgpu_mes_ctx_alloc_meta_data() fails, we should call amdgpu_vm_fini()
to handle amdgpu_vm_init().

Add a new lable before amdgpu_vm_init() and goto this lable when
amdgpu_mes_ctx_alloc_meta_data() fails.
