Module Name:    src

Modified Files:
        src/sys/kern: tty.c

Log Message:
ttycheckoutq(9): wait is always 0.  Assert it; prune dead branches.

There appear to have been no callers with wait=1 since NetBSD 1.0
from a cursory search.  Let's nix the parameter altogether on the
next kernel revbump.  This logic is probably broken anyway in the
presence of ttycancel, which is necessary for, e.g., yanking USB
serial adapters.
