[PATCH rtw-next 14/16] wifi: rtw89: suspend DIG when remain-on-channel

[Ping-Ke Shih <pkshih@realtek.com>]

From: Chih-Kang Chang <gary.chang@realtek.com>

The PD (Packet Detection) lower bound is set after the STA interface
connects. When the P2P interface attempts to find peers, it enters
the remain-on-channel flow to listen for probe requests. However, if
the RSSI of the connected AP is too high, the P2P interface fails to
receive it. To resolve this, suspend the DIG during the
remain-on-channel period.
