'service named reload' does not work correctly when 'pid-file' is configured in named.conf

Issue

• If parameter except for '/var/named/chroot/var/run/named/' is configured as pid-file in named.conf, 'service named reload' does not work correctly.
• It occurs even if it is latest bind version. However, bind97 works correctly.

• Steps to Reproduce:
  1 Add following line in named.conf.

  pid-file "data/named.pid";
  

  2 Start bind.

  # service named start
  Starting named:                                            [  OK  ]
  

  3 Reload named service.

  # service named reload
  Reloading named:                                           [FAILED]
