[PATCH] DAC960: Don't look at PCI_Device->irq before calling pci_enable_device().

The DAC960 driver looks at PCI_Device->irq before calling
pci_enable_device(), which means it requests the wrong IRQ and hangs.
This fixes it. 

Thanks to Johannes Rommel for reporting the problem and testing the fix.
