bond: Simplify bond device destruction
Manually inline the code from bond_deinit to bond_uninit. bond_uninit is the only caller and it is short. Move the call of bond_release_all from the netdev notifier into bond_uninit. The call site is effectively the same and performing the call explicitly allows all the paths for destroying a bonding device to behave the same way. Signed-off-by: Eric W. Biederman <ebiederm@aristanetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
