Mike Travis eee5715efd x86/platform/UV: Fix panic with missing UVsystab support
Fix the panic where KEXEC'd kernel does not have access to EFI runtime
mappings.  This may cause the extended UVsystab to not be available.
The solution is to revert to non-UV mode and continue with limited
capabilities.
