[Piglit] [PATCH] gen_delete_while_active: glEndQuery can be called even if the query has been deleted.

Section 5.1.3 of the spec specifies that the underlying query object is
freed when
it is not longer the active query object for a target. glDeleteQueries
doesn't specify
that the query is no longer the active query for the target (if it was). So
when doing
glEndQuery after having deleted the query name there still is an active
query for the
target with a "non 0 name" even if the name has been deleted.
