[Xen-devel] [PATCH] linux/PCI-MSI: fix compiler warnings resulting from c/s 790

["Jan Beulich" <jbeulich@xxxxxxxxxx>]

The one in pci_enable_msix() is rather meaningful, as the uninitialized
inner msi_dev_entry was indeed hiding the initialized outer one.

As usual, written and tested on 2.6.29-rc8 and made apply to the 2.6.18
tree without further testing.
