Greg Kroah-Hartman e974e8f1e3 PM: EM: fix memory leak with using debugfs_lookup()
[ Upstream commit a0e8c13ccd ]

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.
