qcacmn: Update credit flow control enable/disable in HTC

Browse Source 
There are two ways to enable/disable HTC credit flow control. One is
in HTC itself with a static variable. The other is from the modules
who want to establish HTC service (e.g. WMI or HTT) by sending the
request. Make sure credit flow control enable/disable can be safely
done by other modules so that HTC layer can be converged.
