Farhan Ali 231c7a57d1 PCI/MSI: Enable memory decoding before restoring MSI-X messages ... The current MSI-X restoration path assumes the Command register Memory bit is enabled when writing MSI-X messages. But it's possible the last saved and restored state of a device may not have the Memory bit enabled, even if a device driver later enables Memory bit and MSI-X. Attempting to access Memory space without Memory bit enabled can lead to Unsupported Request (UR) from the device. Fix this by enabling Memory bit and restore it afterwards.
