Jon Shallow 21fd838dc7 coap_io_prepare_io: Re-order function code for correctly updating sockets[] ...

Two cases for not updating active sockets[] with file descriptors from a
session (non epoll code)
  coap_retransmit() can release a session
  coap_dtls_handle_timeout() can disconnect a session

Move the restransmit test code to before any updates to socket[].

Update coap_dtls_handle_timeout() to return a value indicating a DTLS timeout
has occurred.  At the same time move the coap_dtls_handle_timeout() checks
into the first sessions iteration loop, removing having to iterate through the
sessions twice if DTLS.
