accel/amdxdna: Fix uninitialized return value

Browse source

[ Upstream commit 81233d5419 ]

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.
