Monitor: fix inconsistencies in values for ->percent
->percent sometimes stores negative values recording states like 'pending' or 'delayed'. The value '-2' means both 'delayed' and in Monitor, 'unknown'. Also, '-1' has a meaning but not #define. So change the #defines to be prefixed with "RESYNC_", instead of "PROCESS_", add new "_NONE" and "_UNKNOWN", and use correct value in each location. Signed-off-by: NeilBrown <neilb@suse.de>
