KVM: arm64: Refactor user_mem_abort() calculation of force_pte

To simplify the code and to make the assumptions clearer,
refactor user_mem_abort() by immediately setting force_pte to
true if the conditions are met. Also, remove the comment about
logging_active being guaranteed to never be true for VM_PFNMAP
memslots, since it's not technically correct right now.

No functional change intended.
