genl: genl_ctrl_grp_by_name: fix retval in case group id not found

Now the return value in case group id is not find is 0. Change it to
return -NLE_OBJ_NOTFOUND which makes more sense. This should not break
anything because genl_ctrl_grp_by_name is static and called only from
genl_ctrl_resolve_grp. genl_ctrl_resolve_grp already might return
-NLE_OBJ_NOTFOUND.
