Comment # 1 on bug 9033 from Evan Huus

Applying the prefs is triggering rescan_packets which is triggering wmem to
enter file scope.

There are probably two issues here:
- rescan_packets should bail because there is no file open
- if it doesn't bail, it should clean up the epan it creates so that wmem
leaves file scope

CCing Jakub; since this doesn't happen in 1.10 I suspect his epan_new changes
triggered this.
