mesa: Fix error code generation in glBeginConditionalRender()

Browse source 
This patch changes the error condition to satisfy below statement
from OpenGL 4.3 core specification:
"An INVALID_OPERATION error is generated if id is the name of a query
object with a target other SAMPLES_PASSED, ANY_SAMPLES_PASSED, or
ANY_SAMPLES_PASSED_CONSERVATIVE, or if id is the name of a query
currently in progress."
