staging: comedi: addi-data: remove irq parameter from i_pci_card_data()

Browse Source 
The irq parameter passed to i_pci_card_data() is used to get the pci_dev
irq that is cached in the card data. This information can easily be found
when needed in i_ADDI_Attach() from the 'card' pointer to the card data.
