Need your crashing module binary (file ipt_NETFLOW.ko) to investigate further.

ps. It looked like memory corruption. Which could happen in other place, that why fault is in the lock code, lock is possibly corrupted, then netflow_scan_and_export crashes when try to use corrupted lock. Not necessarily netflow_scan_and_export is related in any way with the cause of corruption. (Not necessarily not, of course. It just mean that it is not obvious.)

Other (maybe even preferred) option is to use newer module (you are using very old version + some 'dirty' patches. Why your source is dirty? Maybe you introduced bug yourself while hacking.) There is at least 2.0.1 release, or git head (which should be quite stable too).
And third option is you may have RAM corrupted, you may wish to test RAM chips with memtest+.
