Luiz Augusto von Dentz 31a288a4df Bluetooth: L2CAP: Fix potential user-after-free
[ Upstream commit df57033488 ]

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.
