pppd: Do not clobber exit codes on hangup
When a modem hangup occurs, pppd unconditionally sets the exit status code
to EXIT_HANGUP. This patch only sets EXIT_HANGUP if the exit status code is
not already set to an error value.
The motiviation of this patch is to allow applications which remote control
pppd to react properly on errors, e.g. only redial (relaunch pppd) if there
was a hangup, but not if the CHAP authentication failed.
