PATCH 1/1 wifi: rtw89: leave idle mode when setting WEP encryption for AP mode

From: Dian-Syuan Yang <[email protected]>

Due to mac80211 triggering the hardware to enter idle mode, it fails to install WEP key causing connected station can't ping successfully. Currently, it forces the hardware to leave idle mode before driver adding WEP keys.
