The included patch fixes compilation failure due to a few compiler
warnings when shadow mode debugging/verbose logging is enabled. It
should have no effect when debugging is disabled.

Fix compiler warnings when shadow debugging is enabled.
Fix two classes of warnings when debugging of shadow code is enabled:
- The type_info field in pfn_info is a long, so use a %lx format
specifier when printing it.
- Fix a warning about uninitialized use of eff_guest_pte.
