qcacmn: Increment htc runtime cnt prior to hif_send_head

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.
