MSI: Simplify BUG() handling in msi_remove_pci_irq_vectors() part 2
Although it might be nice to do a printk before BUG'ing, it's really not
necessary, and it complicates the code.
The behaviour has changed slightly, in that before we set a flag if the irq
had an action, and continued freeing the other irqs. But as I see it that's
all irrelevant because we end up BUG'ing anyway.
