modules/rkt: fix scener send error handling

Silly typo, one of those fun C instances where it's surprising
how silently mostly-working such a blatant mistake can be.

For posterity:

The way this was even observed as having an affect is while
verifying graceful handling of connections broken while in the
listen backlog.

With an active scener session idle at the prompt, start another
telnet, connecting without receiving any banner (queued via
backlog), ^]cl that backlogged telnet.   Then start another
telnet in the same way.  Now go to the idle scener session and
quit.  The latest telnet would just sit there, seemingly blocked
behind the broken-while-backlogged connection.

But what was really happening was the banner send got the error
on the broken connection after accepting, as you'd expect.  This
bug in the errno tests prevented detecting the genuine error
though, leaving the broken session connected indefinitely.

Fun!
