qcacmn: Fix core_ctl_set_boost "off" ref count

In current implementation, we may call core_ctl_set_boost(false) even
if its already been turned off an a previous occasion. This leads to
excessive prints in the kmsg "Error turning off boost. Boost already
turned off"

Fix the ref_count such that we donot call the API to turn
core_ctl_set_boost "off", if it is already off.
