[PATCH] kvm/ftrace: change the diplaying format of vector in trace_msi_set_irq

This patch changes the way to diplay the vector in trace_msi_set_irq from %x to
%u.  Currently, it mismatches another output of ftrace such as kvm_msi_set_irq
and kvm_inj_virq which uses %u.

Changing them all to %02x is probably better.  For example, writes to
APIC_ICR will be shown as hex, with the vector in the low order 8 bits,
so it will be easier to match them if they are all in hex.
