net: update netdev stream man page with the reconnect parameter

Browse source 
"-netdev stream" supports a reconnect parameter that attempts to
reconnect automatically the socket if it is disconnected. The code
has been added but the man page has not been updated.

Fixes: 148fbf0d58 ("net: stream: add a new option to automatically reconnect"
