Make conversion from a synced 'mirror' to 'raid1' not cause a full resync.
It was not possible to pass down the DM_[FORCE|NO]SYNC flags to 'dm_tree_node_add_raid_target'. This meant that converting to 'raid1' from 'mirror' would cause a full resync. (It also meant that '--nosync' was ineffective when creating a 'raid1' LV.) I've taken the 'reserved' parameter in 'dm_tree_node_add_raid_target' and used it for the "flags" parameter. Now it is possible to pass the sync flags and any other flags that may come up.
