drivers: hv: vmbus: Increase the time between retries in vmbus_post_msg()
Commit c0bb03924f1a ("Drivers: hv: vmbus: Raise retry/wait limits in
vmbus_post_msg()") increased the retry/wait limits of vmbus_post_msg()
to address the new DoS protection policies in WS2016.
Increase the time between retries to make the
code more robust.
