KVM creates internal memslots covering the region between 3G and 4G in the guest physical address space, when the first vCPU is created. Mapping this region before creation of the first vCPU causes vCPU creation to fail. Prohibit tests from creating such a memslot and fail with a helpful warning when they try to.

The internal memslots are much higher than this (0xfffbc000 and 0xfee00000). I'm changing the patch to block 0xfe0000000 and above, otherwise it breaks vmx_dirty_log_test.
