Subject: [PATCH] drm/amdgpu: Fix the return for gpu mode1_reset
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.
