[PATCH] lock debugging: fix DEBUG_LOCKS_WARN_ON() & debug_locks_silent

Browse Source 
Matthew Wilcox noticed that the debug_locks_silent use should be inverted
in DEBUG_LOCKS_WARN_ON().  This bug was causing spurious stacktraces and
incorrect failures in the locking self-test on the parisc kernel.
