removed dependency of smbd on the smb password database api.

the _only_ function smbd calls is pass_check(), and for some
_weird_ reason, that is in the passdb/ directory.

nasty debugging of an rpcclient incident.  the "usr_creds"
need to be told what they are dealing with (ptr_ntc = 1, for
NT creds to be used).  i forgot.  wasted an hour.
