bnx2: Flush the register writes which setup the MSI-X table
The MSI-X table size needs to be properly set before pci_enable_msix()
is called. But on certain machines, the writes are delayed and the
MSI-X table size is incorrectly read. By reading the
BNX2_PCI_MSIX_CONTROL register, the writes are flushed and now
ensure that the MSI-X table is set correctly before MSI-X
is enable on the device.
