gfapi: increase function-coverage

* Add few more mgmt functions to the coverage
* While testing mgmt function, found an issue, where if the
  'glfs_set_volfile_server()' is not called before calling
  'glfs_unset_volfile_server()', unset would cause a crash.
  Null check of few variables fixes the issue, which is handled
  in this patch itself.
* Added a test for volfile API
