KVM: x86: Move posted interrupt tracepoint to common code
Move the pi_irte_update tracepoint to common x86, and call it whenever the
IRTE is modified. Tracing only the modifications that result in an IRQ
being posted to a vCPU makes the tracepoint useless for debugging.
Drop the vendor specific address; plumbing that into common code isn't
worth the trouble, as the address is meaningless without a whole pile of
other information that isn't provided in any tracepoint.
