removed the wins name registration code from libsmbclient

it is *completely* bogus for our client code to be doing wins
registrations. Not only is it slow as hell (think about when a wins
server is down) but how the heck is going to answer the queries that
will later come in for our name? And what happens when libsmbclient
sends registrations and nmbd then gets the WACK response from the wins
server? we end up losing our name!

Name registration is a job for nmbd, not for clients.
