[BNX2]: Fix suspend/resume problem.
The device would not resume properly if it was shutdown before the system
was suspended. In such scenario where the netif_running state is 0,
bnx2_suspend() would not save the PCI state and so the memory enable bit
and bus master enable bit would be lost.
We fix this by always saving and restoring the PCI state in
bnx2_suspend() and bnx2_resume() regardless of netif_running() state.
Update version to 1.6.4.
