USB: isp1362: fix memory leak with using debugfs_lookup()
[ Upstream commit c26e682afc14caa87d44beed271eec8991e93c65 ] When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call debugfs_lookup_and_remove() instead which handles all of the logic at once.
