Dan Carpenter c4039b29fe efi/libstub: prevent read overflow in find_file_option() ...

If the buffer has slashes up to the end then this will read past the end
of the array.  I don't anticipate that this is an issue for many people
in real life, but it's the right thing to do and it makes static
checkers happy.
