Subject: net: ieee802154: forbid monitor for del llsec key
From: Alexander Aring <aahringo@redhat.com>
[ Upstream commit b6e2949544a183f590ae6f3ef2d1aaaa2c44e38a ]
This patch forbids to del llsec key for monitor interfaces which we
don't support yet. Otherwise we will access llsec mib which isn't
initialized for monitors.
