port-serial: force-close the port if reopen fails
If the reopening operation fails when attempting to recover the
previous open count, it could mean the port is already gone. We didn't
get a HUP in the TTY because the channel I/O monitoring isn't in place
during this time, so this is the best way to detect that at this
point.
And if we do see an error, we'll flag the port as forced closed so
that we do not attempt to reopen it again.
