Should be fixed by the following commit.

    meta: Use internal functions to set texture parameters

    _mesa_texture_parameteriv is used because (the more obvious)
    _mesa_texture_parameteri just stuffs the parameter in an array and calls
    _mesa_texture_parameteriv.  This just cuts out the middleman.

    As a side bonus we no longer need check that ARB_stencil_texturing is
    supported.  The test doesn't allow non-supporting implementations to
    avoid any work, and it's redundant with the value-changed test.

    Fix bug #93717 because the state restore commands at the bottom of
    _mesa_meta_GenerateMipmap no longer depend on the bound state.

    Fixes  piglit   arb_direct_state_access-generatetexturemipmap  with  the
    changes  recently sent  to the  piglit mailing  list.  See  the bugzilla
    entry for more info.
