bnx2x: Prevent probe as early as possible
It's possible that due to errors [either on PCI or on device itself]
registers reads would fail, returning all-Fs.
This adds a check as early as possible so that driver will not read junk
values and make incorrect probe decisions according to them; instead,
gracefully fail the probe.
