HV: hv_balloon: fix memory leak with using debugfs_lookup()
commit 6dfb0771429a63db8561d44147f2bb76f93e1c86 upstream. 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. Cc: "K. Y.
