[PATCH] wifi: rtw88: sdio: copy RX status after updating the frequency

[Hungyu Lin <dennylin0707@gmail.com>]

rtw_sdio_rx_skb() copies rx_status to the skb before calling
rtw_update_rx_freq_for_invalid(). If the frequency is corrected, the skb
still carries the old value when it is passed to mac80211.

Move the copy after the frequency update, as the PCI and USB RX paths
already do.

Built the rtw88 directory on arm64 with GCC 13.3.0 and W=1, with
RTW88_8723BS, RTW88_SDIO, RTW88_PCI and RTW88_USB enabled.

A userspace test of the old and new receive function, with helper calls
stubbed, confirmed that the corrected frequency reaches skb->cb.
No hardware testing.
