When befs_nls2utf() returns an error, the caller ignores the length of the
output buffer since it knows the buffer isn't useful. Removing the
length assignment that will be ignored.

Hi,

Noticed this while continuing to familiarize with the befs code.

As a matter of fact, the only caller of befs_nls2utf() ignores the value of
out_len even when the function succeeds. I was considering that this parameter
could be removed completely.

The only con to doing so I can think of is losing the symmetry with the
matching befs_utf2nls(). Which is why I am asking here before proposing that
patch.

Thanks,
Luis
