This fixes a crash in egl-create-msaa-pbuffer-surface Piglit test and same crash in many dEQP EGL tests.
I also found that some Qt example did a workaround because of this crash: https://bugreports.qt.io/browse/QTBUG-47509 v2: Ian pointed out that v1 removed support for all multisample configs, including window ones. This one removes pbuffer bit when adding configs, now only pbuffer+msaa gets rejected and window+msaa continues to work.
