[Mesa-dev] [PATCH] st/mesa: Initialize tex_target otherwise it might be used uninitialized.

[Gert Wollny]

The initialization of tex_target was dropped and since the value
is used uninitialized (e.g. with Unreal Editor), an assertion
fires in tgsi/tgsi_util.c:502: tgsi_util_get_texture_coord_dim:
  Assertion `!"unknown texture target"' failed.

Initialize tex_target with the enum that corresponds to the value 0 used
before.
