Subject: [PATCH] EFI: suppress bogus loader warning

This was accidentally lost in commit fbc3d9a220 ("EFI: add
efi_arch_handle_cmdline() for processing commandline"), leading to the
"Unknown command line option" warning being printed whenever options
get passed to the core hypervisor or the Dom0 kernel.
