win: Remove a few instances of the "goto error" pattern.

win: Remove a few instances of the "goto error" pattern.

This makes the code simpler, and also fixes a bunch of warnings that look like:

    goto done;
    ^
..\..\remoting\host\win\rdp_client_window.cc(331,14) :
      note(clang): jump bypasses variable initialization
  const LONG kDesiredFlags = WTS_PERF_ENABLE_ENHANCED_GRAPHICS |
             ^
No intended behavior change.
