[Piglit] [PATCH 2/3] arb_get_texture_sub_image: fix depth parameter when performing zero-sized texture queries

[inolen at gmail.com]

From: Anthony Pesch <apesch at nvidia.com>

Change zero-sized texture queries to pass a valid depth parameter, otherwise
they should error as per the OpenGL 4.6 Core spec:

"An INVALID_VALUE error is generated if the effective target is TEXTURE_1D,
TEXTURE_1D_ARRAY, TEXTURE_2D or TEXTURE_RECTANGLE, and either zoffset is not
zero, or depth is not one."
