bnx2: Fix problem of using wrong IRQ handler.
The MSI-X handler was chosen before the call to pci_enable_msix().
If MSI-X was not available, the wrong MSI-X handler would be used in
INTA mode. This would cause a screaming interrupt problem because
INTA would not be cleared by the MSI-X handler.
Fixed by assigning MSI-X handler after pci_enable_msix() returns
successfully. Also update version to 1.9.3.
Thomas Chenault <thomas_chenault@dell.com> helped us find this problem.
