[Bridge] [PATCH net-next 10/15] mlxsw: spectrum_switchdev: Use extack in bridge port flag validation

[Petr Machata]

From: Ido Schimmel <ido...@nvidia.com>

Propagate extack to mlxsw_sp_port_attr_br_pre_flags_set() in order to
communicate error messages related to bridge port flag validation.

Example:

 # bridge link set dev swp1 locked on
 Error: mlxsw_spectrum: Unsupported bridge port flag.

More error messages will be added in subsequent patches.
