bnx2x: save RAM in kdump kernel by disabling TPA
When running in a kdump kernel, disable TPA. This saves memory, which tends to be scarce in kdump. TPA, being a receive acceleration, is unlikely to be useful for kdump, whose purpose is to send the memory image out. This saves additional 5 MB in the kdump environment.
