Subject: net: ieee802154: stop dump llsec params for monitors
From: Alexander Aring <aahringo@xxxxxxxxxx>
commit 1534efc7bbc1121e92c86c2dabebaf2c9dcece19 upstream.
This patch stops dumping llsec params for monitors which we don't support
yet. Otherwise we will access llsec mib which isn't initialized for
monitors.
