qcacmn: Check CAC status on RCAC channel

In case of RCAC, check if CAC is completed only on the RCAC
channel and do not check the CAC info on current operating
channel.

After RCAC complete is sent to FW, the RCAC tree info is
cleared. In case of RCAC, check the CAC done info only
on RCAC channel.
