📄 Description

This PR fixes a bit of logic related to protections, based on tests I wrote in https://github.com/ps4emulation/integration_tests/pull/4

This PR fixes crashing that would occur when calling mprotect on reserved or pool reserved memory, which isn't mapped in address space. On real hardware, mprotect doesn't generally fail.

The changes related to pooled and pool reserved memory are assumptions, I haven't tested them on real hardware yet.
