The socket local pointer needs to be set to NULL when the adapter is
removed or the MAC goes down.
If the socket release code is called after such an event, the socket
reference count still needs to be decreased in order for the socket to
eventually be freed.

When calling nfc_dep_link_up, we implicitely are in initiator mode.
Which means we also can provide the general bytes as a function argument,
as all drivers will eventually request them.

In order to acknowledge an I frame, we have to either queue pending local
I frames or queue a receiver ready frame.

This is a struct sk_buff pointer and it should be freed with kfree_skb()
instead of kfree().

We unlock inside the if block on the other side of this if else
statement. It could result in calling mutex_unlock() twice.

This patch is an initial implementation for the NFC Logical Link Control
protocol. It's also known as NFC peer to peer mode.
This is a basic implementation as it lacks SDP (services Discovery
Protocol), frames aggregation support, and frame rejecion parsing.
Follow up patches will implement those missing features.
This code has been tested against a Nexus S phone implementing LLCP 1.0.
