bnx2: Optimize fast-path tx and rx work.
Add hw_tx_cons_ptr and hw_rx_cons_ptr to speed up the retreival of
the tx and rx consumer index, since the MSI-X and default status
blocks have different structures.
Combine status_blk and status_blk_msix into a union. We'll only use
one type of status block for each vector.
Separate the code to detect more rx and tx work from the code to
detect link related work.
