mesa: Throw an error when starting conditional render on an active query.
From the NV_conditional_render spec:
BeginQuery sets the active query object name for the query type given by
<target> to <id>. If BeginQuery is called with an <id> of zero, if the
active query object name for <target> is non-zero, if <id> is the active
query object name for any query type, or if <id> is the active query
object for condtional rendering (Section 2.X), the error INVALID OPERATION
is generated.
Fixes piglit nv_conditional_render-begin-while-active.
