In the original dc_acquire_release_mpc_3dlut(), only current ctx is
considered, which doesn't fit the steps for atomic checking new ctx.
Therefore, create a function to handle 3D LUT resource for a given
context, so that we can check resources availability in atomic_check
time and handle failures properly.
