Fix a (rare) race condition in mv_interrupt() when using MSI. The value of hpriv->main_irq_mask_addr can change on on the fly, and without this patch we could end up writing back a stale copy to the hardware. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
