[Mesa-dev] [PATCH v2] st/mesa: Fix assertions for copying texture image to finalized miptree.

[Michel Dänzer]

From: Michel Dänzer <michel.daenzer at amd.com>

The layer dimension of array textures is not subject to mipmap minification.
OTOH we were missing an assertion for the depth dimension.

Fixes assertion failures with piglit {f,v}s-textureSize-sampler1DArrayShadow.
For some reason, they only resulted in piglit 'warn' results for me, not
failures.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=56211

NOTE: This is a candidate for the stable branches.

v2: Test for == PIPE_TEXTURE_2D_ARRAY instead of >= PIPE_TEXTURE_1D_ARRAY.
