Introduce a new macro MLXSW_RXL_DIS that allows to register listeners
as disabled. That allows that from now on, the "action" can be
understood always as "enabled action" and "unreg_action" as "disabled
action". Rename them and treat them accordingly.

Use the new macro for defining drops in spectrum_trap.c.

Currently it does not really matter if it is set to DISCARD or
SET_FW_DEFAULT because it is set only during unregister of the listener.
The unreg_action is going to be used for disabling the listener too, so
change to SET_FW_DEFAULT and ensure the HW is going to behave correctly.

After introducing the router lock in previous patches and making sure it
protects internal router structures, we no longer need to rely on RTNL
to serialize access to these structures.

Remove RTNL from call sites that no longer require it.

Two calls sites that keep taking the lock are
mlxsw_sp_router_fibmr_event_work() and mlxsw_sp_inet6addr_event_work().
The first calls into ACL code that still assumes RTNL is taken. The
second potentially calls into the FID code that also relies on RTNL.
Removing RTNL from these two call sites is the subject of future work.
