[PATCH net-next 06/13] mlxsw: spectrum_switchdev: Convert mlxsw_sp_mc_write_mdb_entry() to return int

[Ido Schimmel <idosch@nvidia.com>]

From: Amit Cohen <amcohen@nvidia.com>

The function returns 'false' upon failure and 'true' upon success.
Convert it to the usual scheme of returning integer error codes and
align the callers.
