msm: msm_bus: remove wait on wake/sleep request for disp RSC 



In order to improve the performance for display usecases,
remove the wait_for_completion bits in the TCS commands generated
when sending the batch requests for WAKE and SLEEP sets. This
will also result in a Fire-and-Forget batch request when sent
to RPMH.
