Subject: [PATCH v2] ia64: fix EFI_DEBUG build

When enabled local debugging via `#define EFI_DEBUG 1` noticed
build failure:
    arch/ia64/kernel/efi.c:564:8: error: 'i' undeclared (first use in this function)

While at it fixed benign string format mismatches visible only
when EFI_DEBUG is enabled:

    arch/ia64/kernel/efi.c:589:11:
        warning: format '%lx' expects argument of type 'long unsigned int',
        but argument 5 has type 'u64' {aka 'long long unsigned int'} [-Wformat=]

Fixes: 14fb42090943559 ("efi: Merge EFI system table revision and vendor checks")
