[ Upstream commit 4d7936e8a5b1fa803f4a631d2da4a80fa4f0f37f ]
Reset cookie value to 0 instead of 0xffffffff in hci_sock_free_cookie() since: 0 : means cookie has not been assigned yet 0xffffffff: means cookie assignment failure
Also fix generating cookie failure with usage shown below: hci_sock_gen_cookie(sk) // generate cookie hci_sock_free_cookie(sk) // free cookie hci_sock_gen_cookie(sk) // Can't generate cookie any more
