[LU-18390] Collect memory leak debug log in /tmp/debug correctly

• Type: Improvement
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.17.0
• Severity: 3

Description

In recent memory leak issues, I found the following messages:

LustreError: 277252:0:(class_obd.c:900:obdclass_exit()) obd_memory max: 6549393, leaked: 20
mv: cannot stat '/tmp/debug': No such file or directory
Memory leaks detected

The debug log /tmp/debug doesn't exist because $DEBUG_RMMOD in script lustre_rmmod is not used properly.

I will push a patch to fix it.
