i965/msaa: Set SURFACE_STATE properly when CMS MSAA is in use.

When a buffer using Gen7's CMS MSAA layout is bound to a texture or a
render target, the SURFACE_STATE structure needs to point to the MCS
buffer and to indicate its pitch.  This patch updates the functions
that emit SURFACE_STATE to handle CMS layout properly.
