Explicitly include mmu.h in spte.h instead of relying on the "parent" to
include mmu.h.  spte.h references a variety of macros and variables that
are defined/declared in mmu.h, and so including spte.h before (or instead
of) mmu.h will result in build errors, e.g.

  arch/x86/kvm/mmu/spte.h: In function ‘is_mmio_spte’:
  arch/x86/kvm/mmu/spte.h:242:23: error: ‘enable_mmio_caching’ undeclared
    242 |                likely(enable_mmio_caching);
        |                       ^~~~~~~~~~~~~~~~~~~

  arch/x86/kvm/mmu/spte.h: In function ‘is_large_pte’:
  arch/x86/kvm/mmu/spte.h:302:22: error: ‘PT_PAGE_SIZE_MASK’ undeclared
    302 |         return pte & PT_PAGE_SIZE_MASK;
        |                      ^~~~~~~~~~~~~~~~~

  arch/x86/kvm/mmu/spte.h: In function ‘is_dirty_spte’:
  arch/x86/kvm/mmu/spte.h:332:56: error: ‘PT_WRITABLE_MASK’ undeclared
    332 |         return dirty_mask ? spte & dirty_mask : spte & PT_WRITABLE_MASK;
        |                                                        ^~~~~~~~~~~~~~~~
