qcacmn: Do runtime pm sync resume when printing ring stats

Browse Source 
Printing ring stats from requesting txrx stats needs access PCIe link
so make sure it is resumed by doing a sync resume if it is runtime PM
suspended. Also response of h2t_ext_stats_msg from FW is not guaranteed
so tag it properly so that in HTC layer, corresponding "put" API will
be called right after sending the packet.
