commit 9fea9d6f8e862a8b3f569d37d06d1ff69c6e18f5

egl: Fix the bad surface attributes combination checking for pbuffers. (v3)
Fixes a regression induced by commit
a0674ce5c41903ccd161e89abb149621bfbc40d2:
When EGL_TEXTURE_FORMAT and EGL_TEXTURE_TARGET were both specified (and
both != EGL_NO_TEXTURE), an error was instantly triggered, before the
other one had even a chance to be checked, which is obviously not the
intended behaviour.
v2: Full commit hash, remove useless variables.
v3: [chadv] Add Fixes footers.
Fixes: piglit "spec/egl 1.4/eglcreatepbuffersurface and then glclear"
Fixes: piglit "spec/egl 1.4/largest possible eglcreatepbuffersurface and
then glclear"
