Bugs in the CE sample LSP

I've spent the last few days looking at LSPs and have found
some errors in the sample.

These are:

1. Passing
the wrong WSAPROTOCOLINFO to the next person in the chain:

        Symptom:  WSPSocket 
fails when layered over another LSP.

Fix: DCATALOG::FindNextProviderInChain needs to start by setting      *BaseProviderCatalogEntry=NULL

2. Assuming  *lpErrno == 0:

       Symptom: ssl sockets
(created via SO_SECURE) stop working when layered over ssllsp

       Fix: WSPSelect needs
to start by setting *lpErrno=NO_ERROR.

3. Installing

   I plan on publishing another post on this shortly.
