qcacmn: Increment htc runtime cnt prior to hif_send_head

Browse Source 
HTC runtime count is incremented after posting the HTT
ver req message to CE4. There could be possibility of
processing the ver response message from FW even before
htc_runtime_cnt is incremented. This can casue RTPM put
to not happen causing imbalance in get/put count.

Fix is to increment htc_runtime_cnt before enqueuing
the HTT message to CE.
