bnx2: Fix netpoll crash.
If ->open() and ->close() are called multiple times, the same napi structs
will be added to dev->napi_list multiple times, corrupting the dev->napi_list.
This causes free_netdev() to hang during rmmod.
We fix this by calling netif_napi_del() during ->close().
Also, bnx2_init_napi() must not be in the __devinit section since it is
called by ->open().
