x86: kretprobe-booster interrupt emulation code fix
Fix interrupt emulation code in kretprobe-booster according to
pt_regs update (es/ds change and gs adding).

BTW it's worth to note that there was kretprobe (theoretically cosmetic) change
introduced in v2.6.34-rc1 that wasn't entirely correct:
f007ea2 kprobes/x86: Cleanup save/restore registers
but was fixed in v2.6.35-rc6:
a197479 x86: kprobes: fix swapped segment registers in kretprobe
