qcacld-3.0: update Rx timestamp every time

Host fill netbuf with qtime instead of tsf. In function
"hdd_get_soctime_from_tsf64time", when Host check RX packet
tsf value less than last_target_global_tsf_time, it will
return error. Then, Host will the default value 0 to
upper layer.Sometimes, User will found some packets FW
recvTime is not increasing compared with last packets.
So modify it to calculate qtime from tsf all the time.
