netxen: The driver doesn't work on NX_P3_B1 so cause probe to fail.

I haven't been able to get link up on a NX_P3_B1 since 2.6.31.  The
driver complains about a firmware hang instead.  When I asked I was
told rev 0x41 was a preproduction rev.  So disable support in the
driver so no one is surprised the code doesn't work.
