Revert "w32: On socket nonce mismatch close the socket."

Browse source 
--

The commit was entirely bogus because the check_nonce function closes
the socket itself if it returns with true.  Thus closing the socket by
the caller in the true case was bogus.

The more likely cause for the hangs on Windows are in scdaemon:

  * scd: Fix posssible lockup on Windows due to a lost select
    result.  [rGa7ec3792c5]
