Bluetooth: Simplify Link Key Notification event handling logic
When we get a Link Key Notification HCI event we should already have a
hci_conn object. This should have been created either in the Connection
Request event handler, the hci_connect_acl() function or the
hci_cs_create_conn() function (if the request was not sent by the
kernel).
Since the only case that we'd end up not having a hci_conn in the Link
Key Notification event handler would be essentially broken hardware it's
safe to simply bail out from the function if this happens.

Bluetooth: Track both local and remote L2CAP fixed channel mask
To pave the way for future fixed channels to be added easily we should
track both the local and remote mask on a per-L2CAP connection (struct
l2cap_conn) basis. So far the code has used a global variable in a racy
way which anyway needs fixing.
This patch renames the existing conn->fixed_chan_mask that tracked
the remote mask to conn->remote_fixed_chan and adds a new variable
conn->local_fixed_chan to track the local mask. Since the HS support
info is now available in the local mask we can remove the
conn->hs_enabled variable.

To eliminate the chance for these lockdep warnings we introduce a
nesting level for each channel and use that when acquiring the channel
lock. For now there exists the earlier mentioned three identified

ieee802154: fix iface dump with lowpan
This patch adds a hacked solution for an interface dump with a running
lowpan interface. This will crash because lowpan and wpan interface use
the same arphdr. To change the arphdr will change the UAPI, this patch
checks on mtu which should on lowpan interface always different than
IEEE802154_MTU.
