    elf: Fix comments and logic in _dl_add_to_slotinfo
    
    Since
    
      commit a509eb117fac1d764b15eba64993f4bdb63d7f3c
      Avoid late dlopen failure due to scope, TLS slotinfo updates [BZ #25112]
    
    the generation counter update is not needed in the failure path.
    That commit ensures allocation in _dl_add_to_slotinfo happens before
    the demarcation point in dlopen (it is called twice, first time is for
    allocation only where dlopen can still be reverted on failure, then
    second time actual dtv updates are done which then cannot fail).
