    manage: Make sure c->isfixed is applied before floating checks
    
    Commit 8806b6e23793 ("manage: propertynotify: Reduce cost of unused size
    hints") mistakenly removed an early size hints update that's needed to
    populate c->isfixed for floating checks at manage() time. This resulted
    in fixed (size hint min dimensions == max dimensions) subset of windows
    not floating when they should.
