mlxsw: core: Allow to register disabled traps using MLXSW_RXL_DIS

Browse Source 
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.
