[virtio-dev] [PATCH 2/2] transport-pci: Improve queue msix vector register desc

[Parav Pandit <parav@nvidia.com>]

queue_msix_vector register is for receiving virtqueue notification
interrupts from the device for the virtqueue.

"for MSI-X" is confusing term.

Also it is the register that driver "writes" to, similar to
many other registers such as queue_desc, queue_driver etc.

Hence, replace the verb from use to write.
