drm/amdgpu: handle amdgpu_cgs_create_device() errors in amd_powerplay_create()

Browse source

[ Upstream commit 1435e895d4 ]

Add error handling to propagate amdgpu_cgs_create_device() failures
to the caller. When amdgpu_cgs_create_device() fails, release hwmgr
and return -ENOMEM to prevent null pointer dereference.

[v1]->[v2]: Change error code from -EINVAL to -ENOMEM. Free hwmgr.
