target-i386: Allow interrupt injection after STGI

Browse source 
We need to terminate the translation block after STGI so that pending
interrupts can be injected.

This fixes pending NMI injection for Jailhouse which uses "stgi; clgi"
to open a brief injection window.

Backports commit df2518aa587a0157bbfbc635fe47295629d9914a from qemu
