[BNX2]: Fix race conditions when calling register_netdev().
Hot-plug scripts can call bnx2_open() as soon as register_netdev() is
called in bnx2_init_one(). We need to call pci_set_drvdata() and
setup everything before calling register_netdev(). netif_carrier_off()
also needs to be moved to bnx2_open() to avoid race conditions with
the irq.
