time/debug: Fix memory leak with using debugfs_lookup()
[ Upstream commit 5b268d8abaec6cbd4bd70d062e769098d96670aa ]
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.
