locking/csd_lock: Print large numbers as negatives
The CSD-lock-hold diagnostics from CONFIG_CSD_LOCK_WAIT_DEBUG are
printed in nanoseconds as unsigned long longs, which is a bit obtuse for
human readers when timing bugs result in negative CSD-lock hold times.
Yes, there are some people to whom it is immediately obvious that
18446744073709551615 is really -1, but for the rest of us...
Therefore, print these numbers as signed long longs, making the negative
hold times immediately apparent.
