[PATCH net-next] mlxsw: spectrum_buffers: silence uninitialized warning

Static checkers and runtime checkers such as KMSan will complain that
we do not initialize the last 6 bytes of "cb_priv".  The caller only
uses the first two bytes so it doesn't cause a runtime issue.  Still
worth fixing though.
