kernel: dirty fix for pixel8 wlan/bluetooth. close #1074

The wlan and bluetooth driver bcmdhd4398 cannot be loaded because cfg80211.ko has been converted to a vendor module. You can find more information about this conversion at: ee1e4b7c5e.

The reason why cfg80211.ko cannot be loaded is because the rfkill.ko module in system_dlkm has protected symbols. To fix this issue, we simply need to delete the protected symbol.

"There is no ABI stability between GKI and GKI modules. In order for modules to load correctly during runtime, GKI and GKI modules must be built and updated together."

We need to find a better solution to address this problem.
