[PATCH net-next 2/3] net: netconsole: Eliminate redundant setting of enabled field

[Breno Leitao]

When disabling a netconsole target, enabled_store() is called with
enabled=false. Currently, this results in updating the nt->enabled
field twice:

1. Inside the if/else block, with the target_list_lock spinlock held
2. Later, without the target_list_lock

This patch eliminates the redundancy by setting the field only once,
improving efficiency and reducing potential race conditions.
