KVM: Drop KVM_ERR_PTR_BAD_PAGE and instead return NULL to indicate an error
Remove KVM_ERR_PTR_BAD_PAGE and instead return NULL, as "bad page" is just
a leftover bit of weirdness from days of old when KVM stuffed a "bad" page
into the guest instead of actually handling missing pages. See commit
cea7bb21280e ("KVM: MMU: Make gfn_to_page() always safe").
