[ Upstream commit 81233d5419cf20e4f5ef505882951616888a2ef9 ]
In aie2_get_hwctx_status() and aie2_query_ctx_status_array(), the functions could return an uninitialized value in some cases. Update them to always return 0. The amount of valid results is indicated by the returned buffer_size, element_size, and num_element fields.
