staging: vt6656: s_uCalculateLinkQual use netstats rx values
Use netstats rx_packets and rx_frame_errors.
Add frame errors to RXbBulkInProcessData
The current scStatistic.RxFcsErrCnt only records
USB errors not frame errors.
The scStatistic.RxOkCnt only recorded successful USB
transfers not actual successfully received packets.
So a more accurate reading is to use netstats rx_packets and
rx_frame_errors.
