bnx2x: correct reading of speed capabilities
When the bnx2x driver reads the port configuration - mask irrelevant bits. Without this change, the unintended bits may cause the driver to needlessly toggle the link, as a comparison in the link flap avoidance flow will show that the old link did not advertise the same capabilities and thus cannot be retained.
