KVM: x86/mmu: Rename DEFAULT_SPTE_MMU_WRITEABLE to DEFAULT_SPTE_MMU_WRITABLE

Both "writeable" and "writable" are valid, but we should be consistent
about which we use. DEFAULT_SPTE_MMU_WRITEABLE was the odd one out in
the SPTE code, so rename it to DEFAULT_SPTE_MMU_WRITABLE.

No functional change intended.
