[PATCH v3] drm/amdgpu: Release 'adev->pm.fw' before return in 'amdgpu_device_need_post()'

[Srinivasan Shanmugam]

In function 'amdgpu_device_need_post(struct amdgpu_device *adev)' -
'adev->pm.fw' may not be released before return.

Using the function release_firmware() to release adev->pm.fw.

Thus fixing the below:
drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:1571 amdgpu_device_need_post() warn: 
'adev->pm.fw' from request_firmware() not released on lines: 1554.
