Bluetooth: Trigger SMP for the appropriate LE CoC errors

The insufficient authentication/encryption errors indicate to the L2CAP
client that it should try to elevate the security level. Since there
really isn't any exception to this rule it makes sense to fully handle
it on the kernel side instead of pushing the responsibility to user

This patch adds special handling of these two error codes and calls
smp_conn_security() with the elevated security level if necessary.

that the other places trying to lock parent sockets need to be update to

Bluetooth: Use proper nesting annotation for l2cap_chan lock

that we get warnings if a channel is locked when another one's lock is
tried to be acquired in the same thread. This kind of inter-channel
locking dependencies exist in the form of parent-child channels as well
as any channel wishing to elevate the security by requesting procedures
on the SMP channel.

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
categories: SMP, "normal" channels and parent channels (i.e. those in
BT_LISTEN state). The nesting level is defined as atomic_t since we need

net/bluetooth/amp.c:152:53: warning: Variable length array is used.

The warning itself is probably harmless since this kind of usage of
shash_desc is present also in other places in the kernel (there's even a
convenience macro SHASH_DESC_ON_STACK available for defining such stack
variables). However, dynamically allocated versions are also used in
several places of the kernel (e.g. kernel/kexec.c and lib/digsig.c)
which have the benefit of not exhibiting the sparse warning.

Since there are no more sparse warnings in the Bluetooth subsystem after
fixing this one it is now easier to spot whenever new ones might get
introduced by future patches.
