Luiz Augusto von Dentz b938790e70 Bluetooth: hci_codec: Fix leaking content of local_codecs 
The following memory leak can be observed when the controller supports
codecs which are stored in local_codecs list but the elements are never
freed:

unreferenced object 0xffff88800221d840 (size 32):
  comm "kworker/u3:0", pid 36, jiffies 4294898739 (age 127.060s)
  hex dump (first 32 bytes):
