tg3: prevent use of uninitialized remote_adv and local_adv variables

Browse source

[ Upstream commit 0c3f2e6281 ]

Some execution paths that jump to the fiber_setup_done label
could leave the remote_adv and local_adv variables uninitialized
and then use it.

Initialize this variables at the point of definition to avoid this.
