bridge: implement missing ndo_uninit()
While the bridge driver implements an ndo_init(), it was missing a
symmetric ndo_uninit(), causing the different de-initialization
operations to be scattered around its dellink() and destructor().
Implement a symmetric ndo_uninit() and remove the overlapping operations
from its dellink() and destructor().
This is a prerequisite for the next patch, as it allows us to have a
proper cleanup upon changelink() failure during the bridge's newlink().
