(noticed during preparation of initial PAE-guest-on-64bit patches)
The offset used to compare the return IP was apparently wrong; I
didn't actually test that things didn't work as intended (or that they
do now with this change), it just caught my eye that the UREGS_rip
access a little further up in the same function was done with
adjustment for the extra item on the stack, but this one wasn't.
