locking/lockdep: Avoid unmatched unlock
[ Upstream commit 7f82e631d236cafd28518b998c6d4d8dc2ef68f6 ]
Commit f6f48e180404 ("lockdep: Teach lockdep about "USED" <- "IN-NMI"
inversions") overlooked that print_usage_bug() releases the graph_lock
and called it without the graph lock held.
Fixes: f6f48e180404 ("lockdep: Teach lockdep about "USED" <- "IN-NMI" inversions")
