vm exit during Event Delivery is not triggered by external

This patch fix a external interrupt injecting bug in linux 3.19-rc4.
GuestOS is running and handling some interrupt with RFLAGS.IF = 0 while a
external interrupt coming,
then can lead to a vm exit,in this case,we must avoid inject this external
interrupt or it will generate
a processor
