core: fix offset in assign_mobj_to_param_mem()

Prior to this patch assign_mobj_to_param_mem() stored the offset
supplied with a non-contiguous buffer in mem->offs. Since that offset
already is stored inside the resulting MOBJ that offset is added twice.
This patch fixes this by initializing mem->offs to 0 instead.
