[PATCH 1/1] bonding: Remove unnecessary returned value check

[PATCH 1/1] bonding: Remove unnecessary returned value check

[Zhu Yanjun]

The function bond_info_query alwarys returns 0. As such, in the function
bond_do_ioctl, it is not necessary to check the returned value. So the
interface type of the function bond_info_query is changed to void. The
redundant check is removed.
