-Follow up r17206, transfert *src on status_get_sc_def to properly calculate defense.
nb : 
NULL is transmitted for atcommand and npc call since they shouldn't be reduced.
src = direct user, so we can compare directly, if you want to compare to master please cast so.
saved status from char won't have *src currently since I don't believe we need to recalculate def.
