  KVM: VMX: Cap VMX preemption timer to work around Intel erratum (2026-07-31 13:41:56 -0700)

----------------------------------------------------------------
KVM VMX changes for 7.3

 - Service local TLB flushes on a failed nested VM-Enter to fix a bug where KVM
   could miss a TLB on a future, successful VM-Enter with the same L2 VPID.

 - Cap the maximum value shoved into the VMX Preemption Timer to workaround an
   erratum that affects all existing Intel CPUs that support CPUID 0x15.
