NTB: ntb_transport: fix debugfs_remove_recursive
commit dd62245e73de9138333cb0e7a42c8bc1215c3ce6 upstream.
The call to debugfs_remove_recursive(qp->debugfs_dir) of the sub-level
directory must not be later than
debugfs_remove_recursive(nt_debugfs_dir) of the top-level directory.
Otherwise, the sub-level directory will not exist, and it would be
invalid (panic) to attempt to remove it. This removes the top-level
directory last, after sub-level directories have been cleaned up.
