svga: check number of samples before emitting MSAA decls/opcodes

If real MSAA is not available, we only support 1 sample/pixel.  In that
case, we must not declare MSAA resources or emit MSAA opcodes.  Do that
by checking the sample count.

Fixes several piglit MSAA tests, such as
arb_texture_multisample-sample-depth (when the hard-coded sample count
of 4 is fixed in that test).
