Bluetooth: Fix LE connection timeout deadlock
commit 980ffc0a upstream. The le_conn_timeout() may call hci_le_conn_failed() which in turn may call hci_conn_del(). Trying to use the _sync variant for cancelling the conn timeout from hci_conn_del() could therefore result in a deadlock. This patch converts hci_conn_del() to use the non-sync variant so the deadlock is not possible.
