[Mesa-dev] [PATCH] mesa: support GL_RGB for GL_EXT_texture_type_2_10_10_10_REV

[Tapani Pälli]

Commit 8ec6534 changed texture upload path and the way how texture
format is being checked, this commit adds support for GL_RGB with
GL_UNSIGNED_INT_2_10_10_10_REV as specified by the extension
EXT_texture_type_2_10_10_10_REV specification.

This fixes regression in ES3 conformance test
   ES3-CTS.gtf.GL3Tests.packed_pixels.packed_pixels
