Don't call fixup_filename() on each witness lock call.

This has been irking me for a while. This causes significant
CPU use on bottlenecked CPUs (eg my older EEEPC w/ an earlier
Celeron CPU and my MIPS24k boards) when they're passing
a lot of traffic.

Since the file/line values are only used for printing, this
should only affect display. It should have no operational
change on the code, besides reducing CPU use.
