Greg Kroah-Hartman e974e8f1e3 PM: EM: fix memory leak with using debugfs_lookup() 
[ Upstream commit a0e8c13ccd6a9a636d27353da62c2410c4eca337 ]

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.
