[BNX2]: update version and minor fixes

Update version and add 4 minor fixes, the last 2 were suggested by
Jeff Garzik:

1. check for a valid ethernet address before setting it
2. zero out bp->regview if init_one encounters an error and unmaps
   the IO address. This prevents remove_one from unmapping again.
3. use netif_rx_schedule() instead of hand coding the same.
4. use IRQ_HANDLED and IRQ_NONE.
