USB: gadget: gr_udc: fix memory leak with using debugfs_lookup()
[ Upstream commit 73f4451368663ad28daa67980c6dd11d83b303eb ]
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.
