Starting in Android 11, Android unconditionally disables kernel module autoloading (https://r.android.com/1254748) in such a way that even the SELinux permission does not get checked. Therefore, all the SELinux rules that allow or dontaudit the module_request permission are no longer necessary. Their presence or absence makes no difference. Bug: 130424539 Test: Booted Cuttlefish, no SELinux denials. Change-Id: Ib80e3c8af83478ba2c38d3e8a8ae4e1192786b57
