msm: msm_bus: Adjust active and dual votes to prevent double voting

Sleep votes are currently treated as dual context votes with the
rpmh iteration of the bus driver, change update_bw_adhoc to clear
active ib/ab votes from non active only clients to prevent
a double bandwidth vote. Rename slp_ib/slp_ab to dual_ib/dual_ab
to better describe its purpose.
