Luiz Augusto von Dentz b8ed41cc04 Bluetooth: L2CAP: Fix potential user-after-free
[ Upstream commit df5703348813235874d851934e957c3723d71644 ]

This fixes all instances of which requires to allocate a buffer calling
alloc_skb which may release the chan lock and reacquire later which
makes it possible that the chan is disconnected in the meantime.

Fixes: a6a5568c03 ("Bluetooth: Lock the L2CAP channel when sending")
