rv/monitors: add 'static' qualifier for local symbols

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.

So does wip module.
