commit 2196e945e4ac5f41d6650c4ceb9120cfd8fc8d56

Fix "WHO #<chan>" showing invisible users and hiding all visible

The logic is reversed ...

This bug has been introduced by commit c74115f2, "Simplify mode checking on
channels and users within a channel", ngIRCd releases 21, 21.1, and 22 are
affected :-(

Problem reported by Cahata in #ngircd, Thanks!
