[PATCH] bnx2: turn off the network statck during initialization

The initialization state of bnx2 driver is wrong. It does not turn
of the Linux network stack using netif_carrier_off. This may lead to
inconsistent report from ethtool as the link is up but speed is
unknown when the cable is not plugged in.

E.g.
        Speed: Unknown! (0)<--------------------------------------
        Duplex: Half       <--------------------------------------
        MDI: Unknown! (0)
        Port: Twisted Pair
        PHYAD: 1
        Transceiver: internal
        Auto-negotiation: on
        Supports Wake-on: g
        Wake-on: d
        Link detected: yes <---------------------------------------

This patches fixed the problem by turning off the network stack
during initialization.
