[src/trunk]: src/usr.bin/ftp ftp: remove unnecessary variable assignments

description:
ftp: remove unnecessary variable assignments

Remove assignment to error in initconn(); it's not tested anywhere after the
initial use, so no need to set it before goto bad.

(Looks like copypasta from the initial addition of the code in rev 1.48.)
