drm/amdgpu: Fix the return for gpu mode1_reset

Browse Source 
amdgpu_device_mode1_reset will return gpu mode1_reset
succeed (ret = 0) as long as wait_for_bootloader call
succeed, regardless of the status reported by smu or
psp firmware. This results to driver continue executing
recovery even smu or psp fail to perform mode1 reset.
