[Patch] Don't update DTLS retransmit timer too often

Currently, when the user calls a handshake function on nonblocking DTLS
sessions with no data available, the retransmit timers are updated
without condition in _dtls_wait_and_retransmit. In that case,
_dtls_transmit is also called, and if _dtls_transmit detects a flight
timeout, the timer is updated again. This not only slows down - or
outright disables - flight loss recovery.
