drivers: base: dd: fix memory leak with using debugfs_lookup()
[ Upstream commit 36c893d3a759ae7c91ee7d4871ebfc7504f08c40 ]
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.
