egl: propagate EGL_BAD_ATTRIBUTE during EGLImage attr parsing

Earlier commit refactored/split the parsing into separate hunks.
While no functional change was intended, it did not attribute that
different error is set when the attrib. value is incorrect.

Fixes:  3ee2be4113 ("egl: split _eglParseImageAttribList into per
extension functions")
