Subject: [PATCH net-next v3 12/15] mlxsw: spectrum_trap: Do not initialize dedicated discard policer

From: Ido Schimmel <idosch@...lanox.com>

The policer is now initialized as part of the registration with devlink,
so there is no need to initialize it before the registration.

Remove the initialization.
