[PATCH user-cr] return, don't exist, at coord error

["Serge E. Hallyn" <serue-r/Jw6+rmf7HQT0dZR+AlfA@public.gmane.org>]

All right I can't explain it at the moment, but exit(1) at
ckpt_coordinator() (on error) causes restart.c to exit with 0,
whereas return(ret) causes it to correctly exit with -1.

Without this, a restart whose kernel portion ends with say
-1 ends up returning from user-cr/restart.c with 0, so userspace
can't tell whether sys_restart succeeded or failed.  With the
patch, it fails correctly.
