qcacmn: Add support for STA inactive time in Hawkeye

Currently there is not STA inactive time support for lithium.
Read inactive_time from htt_peer_stats_cmn_tlv by sending
HTT_DBG_EXT_STATS_PEER_INFO to firmware.
After sending command, wait on completion variable till
firmware to response, trigger completion upon firmware response.
