drm/amdgpu: cleanup ctx implementation

Browse Source 
Let each context have a pointer to the ctx manager and properly
initialize the adev pointer inside the context manager.

Reduce the BUG_ON() in amdgpu_ctx_add_fence() into a WARN_ON() and
directly return the sequence number instead of writing into a parmeter.
