[ Upstream commit 4d7936e8a5 ]
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
