Subject: [PATCH] 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.
