Does commenting out the "GL_EXT_texture_sRGB_decode" entry in gl_extension_map[] (wined3d/directx.c) make any difference? Otherwise it should be possible to disable the GL extension via the MESA_EXTENSION_OVERRIDE environment variable (so something like MESA_EXTENSION_OVERRIDE="-GL_EXT_texture_sRGB_decode" wine ...), that should have the same effect as the code change I suggested.
Using MESA_EXTENSION_OVERRIDE does result in "Init OK" while without it I get the error.
