Subject: [PATCH 2/2] transport-pci: Improve queue msix vector register desc
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.
