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.
