PCI: make msi_free_irqs() to use msix_mask_irq() instead of open coded write
Use msix_mask_irq() instead of direct use of writel, so as not to clear preserved bits in the Vector Control register [31:1]. Signed-off-by: Hidetoshi Seto <seto.hidetoshi@jp.fujitsu.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
