[PATCH 3.16.y-ckt 008/216] KVM: s390: Fix size of monitor-class number field

[Luis Henriques]

3.16.7-ckt4 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thomas Huth <thuth@xxxxxxxxxxxxxxxxxx>

commit a36c5393266222129ce6f622e3bc3fb5463f290c upstream.

The monitor-class number field is only 16 bits, so we have to use
a u16 pointer to access it.
