KVM: x86/mmu: Drop access tracking checks when clearing TDP MMU dirty bits

Browse source

Drop the unnecessary call to handle access-tracking changes when clearing
the dirty status of TDP MMU SPTEs.  Neither the Dirty bit nor the Writable
bit has any impact on the accessed state of a page, i.e. clearing only
the aforementioned bits doesn't make an accessed SPTE suddently not
accessed.
