[driver] patchguard complicit issues? #2

Description

@NextrixVFX

conceptually the driver is great (excluding the lack of exception handling everywhere, and hardcoded cr3), but im pretty sure the kep hooks and callbacks aren't patchguard compliant. results in a bluescreen when using communication / the hooked(kep) exports are called / possibly more.
however, the etw hooking is fine, and maybe the shadow mapping (create_hyperspace + remap_hyperspace) is fine, but that's about it.

anywhere where an "unused" region of memory is overwritten with shellcode will eventually cause a stack corruption with a bugcheck 4 code of 0 when patchguard checks the nt image. though, i might be wrong; i'm not like einstein with the windows kernel.
