[PATCH -next] trace: wwnr: Make local symbol 'rv_wwnr' static

[Zeng Heng]

The sparse tool complains as follows:

kernel/trace/rv/monitors/wwnr/wwnr.c:18:19:
warning: symbol 'rv_wwnr' was not declared. Should it be static?

The `rv_wwnr` symbol is not dereferenced by other extern files,
so add static qualifier for it.
