drm/amdgpu: partial revert "remove ctx->lock" v2

Browse Source 
This reverts commit 461fa7b0ac.

We are missing some inter dependencies here so re-introduce the lock
until we have figured out what's missing. Just drop/retake it while
adding dependencies.

v2: still drop the lock while adding dependencies
