s3: fix guest auth when winbindd is running
This fix is very subtle. If a server is configured with "security = share" and "guest ok = yes" and winbindd is running authorization will fail during tree connect. This is due to our inability to map the guest sid S-1-5-21-X-501 to a uid through sid_to_uid(). Winbindd is unaware of the hard coded mapping between this sid and whatever uid the name in lp_guestaccount() is assigned. So sid_to_uid() fails and we exit create_token_from_username() without ever calling pdb_getsampwsid() which IS aware of the hard coded mapping. This patch just reorganizes the code, moving sid_to_uid() down to the block of code in which it is needed, avoiding this early failure. (cherry picked from commit 671812696217fe1337562b661d5131be79797f1c)
