tg3: Fix single-vector MSI-X code
Kdump kernels leave MSI-X interrupts (as setup by the crashed kernel) enabled. However, kdump only enables one CPU in the new environment, thus causing tg3 to abort MSI-X setup. When the driver attempts to enable INTA or MSI interrupt modes on a kdump kernel, interrupt delivery fails. This patch attempts to workaround the problem by forcing the driver to enable a single MSI-X interrupt. In such a configuration, the device's multivector interrupt mode must be disabled.
