[PATCH][2.2] eepro100 - gracefully handle init_etherdev failure

[Neale Banks]

Greetings,

Appended patch against 2.2.21pre2 is for eepro100 to gracefully handle the
case where init_etherdev() returns NULL.

BTW, in testing this the unpatched eepro100 driver module apeared to get
wedged in an initialising status - is this normal?

Regards,
Neale.
