[sky2] Fix sky2 network driver suspend/resume
This fixes two independent problems: it would not save the PCI state on suspend (and thus try to resume a nonexistent state on resume), and while shut off, if an interrupt happened on the same shared irq, the irq handler would react very badly to the interrupt status being an invalid all-ones state.
