8390: Don't oops on starting dev queue

The __NS8390_init tries to start the device queue before the
device is registered. This results in an oops (snipped):

This happens because the netif_start_queue sets respective bit on the dev->_tx
array which is not yet allocated.

As far as I understand the code removing the netif_start_queue from __NS8390_init
is OK, since queue will be started later on device open. Plz, correct me if I'm wrong.

Found in the Dave's current tree, so he's in Cc.
