Subject: mlxsw: spectrum_trap: Do not initialize dedicated discard policer
Patch-mainline: v5.7-rc1
Git-commit: bc82521e3b8e8cfa7e0136080c75a3af3a1b448a
References: bsc#1176774

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.
