Greg Kroah-Hartman cc00340fb1 USB: fix memory leak with using debugfs_lookup() 
[ Upstream commit 30374434ed ]

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.
