Brian King dd9c20fa07 ibmvnic: Disable irq prior to close ... Add some code to call disable_irq on all the vnic interface's irqs. This fixes a crash observed when closing an active interface, as seen in the oops below when we try to access a buffer in the interrupt handler which we've already freed.
