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.
