vdpa/mlx5: Add and remove debugfs in setup/teardown driver

The right place to add the debugfs create is in
setup_driver() and remove it in teardown_driver().

Current code adds the debugfs when creating the device but resetting a
device will remove the debugfs subtree and subsequent set_driver will
not be able to create the files since the debugfs pointer is NULL.
