Shradha Gupta eaeea5028f net: mana: Cleanup "mana" debugfs dir after cleanup of all children 
In mana_driver_exit(), mana_debugfs_root gets cleanup before any of it's
children (which happens later in the pci_unregister_driver()).
Due to this, when mana driver is configured as a module and rmmod is
invoked, following stack gets printed along with failure in rmmod command.
