examples: Updated asiohiper.cpp to remove connect from opensocket

Browse Source 
Blocking connect on the socket has been removed from opensocket
callback. opensocket just opens a new socket and gives it back to
libcurl and libcurl will take care of the connect. sockopt_callback has
also been removed, as it is no longer required.
