btrfs-progs: rename struct open_ctree_flags to open_ctree_args

Browse Source 
The struct open_ctree_flags currently holds arguments for
open_ctree_fs_info(), it can be confusing when mixed with a local variable
named open_ctree_flags as below in the function cmd_inspect_dump_tree().

  cmd_inspect_dump_tree()
  ::
  struct open_ctree_flags ocf = { 0 };
  ::
  unsigned open_ctree_flags;

So rename struct open_ctree_flags to struct open_ctree_args.
