[Mesa-dev] [PATCH v2] egl/dri2: dri2_make_current: Set EGL error if bindContext fails

[Nicolas Boichat]

From: Nicolas Boichat <drinkcat at chromium.org>

Without this, if a configuration is, say, available only on GLES2/3, but
not on GLES1, and is rejected by the dri module's bindContext call,
eglMakeCurrent fails with error "EGL_SUCCESS".

In this patch, we set error to EGL_BAD_MATCH, which is what CTS/dEQP
dEQP-EGL.functional.surfaceless_context expect.
