[RFCv5 00/16] Bluetooth: Change socket lock to l2cap_chan lock

[Emeltchenko Andrei <Andrei.Emeltchenko.news@gmail.com>]

From: Andrei Emeltchenko <andrei.emeltchenko@intel.com>

This set is still WIP, hope to send PATCH series next week.

Those patches which dealing with locks need to be applied at once,
if needed they can be merged together.

Changes:
	* RFCv5: Fixed locking bug in l2cap_data_channel, added locks in 
	l2cap_sock_shutdown function, fixed several styles issues.
	* RFCv4: Better split patches so they looks more clear and obvious,
	taking coments about naming change and delete unused vars. See diff change
	from the previous version below:
	* RFCv3: Split the big patch to several small (I believe logical) chunks,
	remove unneded locks from cleanup_listen, use the same arguments for
	locked/unlocked socket error functions.
	* RFCv2: Convert l2cap channel list back to mutex from RCU list.
