net: microchip: sparx5: prevent uninitialized variable

Browse Source 
Smatch complains that:

    drivers/net/ethernet/microchip/sparx5/sparx5_dcb.c:112
    sparx5_dcb_apptrust_validate() error: uninitialized symbol 'match'.

This would only happen if the:

	if (sparx5_dcb_apptrust_policies[i].nselectors != nselectors)

condition is always true (they are not equal).  The "nselectors"
variable comes from dcbnl_ieee_set() and it is a number between 0-256.
This seems like a probably a real bug.
