Before, if the depth test is disabled, but depthCompareOp is VK_COMPARE_OP_NEVER (e.g. from the app having zero-initialized the structure), then sanitize_stencil_face() would have incorrectly changed passOp to VK_STENCIL_OP_KEEP. v2: Roll the depthTestEnable check into the ds_aspect check below since they now both do the same thing.
