CVE-2023-53355

When calling debugfslookup() the result must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call debugfslookupandremove() instead which handles all of the logic at once. This requires saving off the root directory dentry to make creation of individual device subdirectories easier.
