x86/efi: Fix earlyprintk off-by-one bug
Dave reported seeing the following incorrect output on his Thinkpad T420
when using earlyprintk=efi,
[ 0.000000] efi: EFI v2.00 by Lenovo
ACPI=0xdabfe000 ACPI 2.0=0xdabfe014 SMBIOS=0xdaa9e000
The output should be on one line, not split over two. The cause is an
off-by-one error when checking that the efi_y coordinate hasn't been
incremented out of bounds.
