kernel/irq/irqdomain.c: fix memory leak with using debugfs_lookup()
commit d83d7ed260283560700d4034a80baad46620481b 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.
