    drivers: base: component: fix memory leak with using debugfs_lookup()
    
    [ Upstream commit 8deb87b1e810dd558371e88ffd44339fbef27870 ]
    
    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.
