s3-passdb: Remove unused sampass->pass_must_change_time

There is no need to call pdb_set_pass_must_change_time() because
nothing ever consults that value.  It is always calculated from the
domain policy.

Also, this means we no longer store the value in LDAP.  The value
would only ever be set when migrating from tdbsam or smbpasswd, not on
password changes, so would become incorrect over time.
