KVM: rename is_writeble_pte() to is_writable_pte()

Browse Source 
There are two spellings of "writable" in
arch/x86/kvm/mmu.c and paging_tmpl.h .

This patch renames is_writeble_pte() to is_writable_pte()
and makes grepping easy.

  New name is consistent with the definition of itself:
  return pte & PT_WRITABLE_MASK;
