Fix minor TTY API inconsistency.

Unlike tty_rel_gone() and tty_rel_sess(), the tty_rel_pgrp() routine
does not unlock the TTY. I once had the idea to make the code call
tty_rel_pgrp() and tty_rel_sess(), picking up the TTY lock once. This
turned out a little harder than I expected, so this is how it works now.

It's a lot easier if we just let tty_rel_pgrp() unlock the TTY, because
the other routines do this anyway.
