hv: vlapic: add vector check for x2apic SELF IPI 

Set when the local APIC detects an illegal vector (one in the range 0 to 15)
in the message that it is sending. This occurs as the result of a write to the
ICR (in both xAPIC and x2APIC modes) or to SELF IPI register (x2APIC mode only)
with an illegal vector.
