meta: Actually initialize ImmutableLevels to 1.
Otherwise, ImmutableLevels is 0, which is an illegal value. Later,
_mesa_meta_setup_sampler will use _mesa_texture_parameteriv to set
texObj->MaxLevel = CLAMP(params[0], texObj->BaseLevel,
texObj->ImmutableLevels - 1);
which turns into a completely bogus CLAMP(value, 0, -1)...where the
upper bound is smaller than the lower bound. This ends up being -1
today due to the way CLAMP is implemented, which is a bogus MaxLevel.
