soc: qcom: llcc: Check return value on Broadcast_OR reg read
Commit c72ca343f911 ("soc: qcom: llcc: Add v4.1 HW version support") introduced a new 4.1 if statement in llcc_update_act_ctrl() without considering that ret might be overwritten. So, add return value check after Broadcast_OR register read in llcc_update_act_ctrl().
