accel/amdxdna: Fix uninitialized return value

Browse Source 
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.

Fixes: 2f509fe6a4 ("accel/amdxdna: Add ioctl DRM_IOCTL_AMDXDNA_GET_ARRAY")
