[Mesa-dev] [PATCH 4/6] mesa/es3.1 : Correct error code for defect texture target

[Marta Lofstedt]

From: Marta Lofstedt <marta.lofstedt at intel.com>

According to GLES 3.1 CTS test:
ES31-CTS.texture_storage_multisample.
APIGLGetTexLevelParameterifv.
invalid_texture_target_rejected:

GL_INVALID_ENUM should be generated when
glGetTexLevelParameteriv is called with a defect
texture target.
