Subject: net: ieee802154: forbid monitor for del llsec seclevel
From: Alexander Aring <aahringo@xxxxxxxxxx>
commit 9dde130937e95b72adfae64ab21d6e7e707e2dac upstream.
This patch forbids to del llsec seclevel for monitor interfaces which we
don't support yet. Otherwise we will access llsec mib which isn't
initialized for monitors.
