KVM: x86/mmu: Drop redundant trace_kvm_mmu_set_spte() in the TDP MMU

mainline inclusion
from mainline-v5.13-rc1
commit 3849e092
category: feature
bugzilla: https://gitee.com/openeuler/intel-kernel/issues/I7S3VQ
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3849e0924ef14a245aa292ecaa9accdc4792012c



----------------------------------------------------------------------

Remove TDP MMU's call to trace_kvm_mmu_set_spte() that is done for both
shadow-present SPTEs and MMIO SPTEs.  It's fully redundant for the
former, and unnecessary for the latter.  This aligns TDP MMU tracing
behavior with that of the legacy MMU.
