[PATCH v2] wifi: rtw88: 8723b: avoid converting RX SNR twice

[Hungyu Lin]

rtw8723b_query_phy_status_ofdm() divides the SNR report by two when
filling pkt_stat->rx_snr, then shifts it again when updating
dm_info->rx_snr. This halves the SNR used for diagnostics and average
statistics.

Store the raw report in pkt_stat->rx_snr and convert it only when
updating dm_info->rx_snr, as the other chip drivers do.

Fixes: d726c70ce082 ("wifi: rtw88: 8723b: add the RTL8723B chip driver")

Changes in v2:
- Store the raw SNR report in pkt_stat->rx_snr and keep the shift when
  updating dm_info->rx_snr.
