[Mesa-dev] [PATCH 2/3] mesa: remove _mesa_get_tex_unit_err() and fix error handling

This helper was only called from _mesa_BindTextureUnit(). It's simpler
to just inline it.
The error check / code / message in the helper was incorrect. It was
written for glBindTextures(), not glBindTextureUnit(). The correct
error for a bad texture unit number is GL_INVALID_VALUE. The error
message now reports the unit number rather than a GL_TEXTUREi enum.
Fixes a failure in piglit's arb_direct_state_access-bind-texture-unit test.
