[Mesa-stable] [PATCH] Mesa: Fix error code for glTexImage3D in GLES

From: "Xu,Randy" <randy.xu at intel.com>

The ES specification says that TexImage3D should return GL_INVALID_OPERATION
if the internal format is DEPTH_COMPONENT, DEPTH_-STENCIL or STENCIL_INDEX.
The current code returns INVALID_ENUM as _mesa_error_check_format_and_type is
used by glReadPixels also and the GL specification defines "INVALID_ENUM is
generated if format is DEPTH_STENCIL and type is not UNSIGNED_INT_24_8 or
FLOAT_32_UNSIGNED_INT_24_8_- REV".

This patch only impacts GLES, which can generate GL_INVALID_OPERATION because
glReadPixels cannot be used to read depth or stencil buffer.
Fixes dEQP-GLES3.functional.negative_api.texture.teximage3d.
