mesa/es3.1 : Align OpenGL ES 3.1 glBindVertexBuffer error handling with OpenGL Core

According to OpenGL ES 3.1 specification 10.3.1:
"An INVALID_OPERATION error is generated if buffer is not zero
or a name returned from a previous call to GenBuffers,
or if such a name has since been deleted with DeleteBuffers."
This error check was previously limited to OpenGL Core.
