emacs-29 2bad5829ff7: Revert "Fix parsing of dn line if WITHDN is non-nil"

[Filipp Gunbin]

branch: emacs-29
commit 2bad5829ff76538774676f7274f40ce7baf04c73
Author: Filipp Gunbin <fgunbin@fastmail.fm>

    Revert "Fix parsing of dn line if WITHDN is non-nil"
    
    This reverts commits 71b27779a9a and d2246b26275, because they change
    the return value of "ldap-search" in an incompatible way.  The fix
    (a different one) will be done on master instead (bug#64089).
