Subject: Drivers: hv: vmbus: Change server monitor_pages index to 0
Git-commit: fd8e3c35b4dfafe10278c5f6d48190b5bbf26b40
References: fate#323887

Change the monitor_pages index in server_monitor_pending_show() to '0'.
'0' is the correct monitor_pages index for the server. A comment for the
monitor_pages field in the vmbus_connection struct definition indicates
that the 1st page is for parent->child notifications. In addition, the
server_monitor_latency_show() and server_monitor_conn_id_show()
functions use monitor_pages index '0'.
