Re: [PATCH] xen: Remove unnecessary BUG_ON from __unbind_from_irq()

Commit 910f8befdf5b ("xen/pirq: fix error path cleanup when binding MSIs") fixed a couple of errors in error cleanup path of xen_bind_pirq_msi_to_irq(). This cleanup allowed a call to __unbind_from_irq() with an unbound irq, which would result in triggering the BUG_ON there.

Since there is really no reason for the BUG_ON (xen_free_irq() can operate on unbound irqs) we can remove it.
