This patch does some code refactoring in hci_cs_le_create_conn
function. The hci_conn object is only needed in case of failure,
therefore hdev locking and hci_conn lookup were moved to
if-statement scope.
Also, the conn->state check was removed since we should always
close the connection if it fails.
