x86/shadow: Drop stale adjustment in the PAE second-half search

This shouldn't have been present in c/s 29a57c992 "x86/emul: Rework emulator
event injection".  It was a leftover from a previous version of the series.

This conditional has no effect on the behaviour following it, as both
X86EMUL_EXCEPTION and X86EMUL_UNHANDLEABLE fall into the same "return back to
guest" path.
