perf kmem: Fix compiler warning about may be accessing uninitialized variable
The last argument to strtok_r doesn't need to be initialized, its just a
placeholder to make this routine reentrant, but gcc doesn't know about
that and complains, breaking the build, fix it by setting it to NULL.
Fixes: 0e11115644b3 ("perf kmem: Print gfp flags in human readable string")
