[PATCH 15/15] libtracefs: initialize val in build_filter()

In build_filter(), val is only initialized if filter->rval->type is
either EXPR_NUMBER or EXPR_STRING. AS far as I can understand that is
expected at that point. Howvever, it doesn't cost much to initialize
it in case the parser let some bogus request pass by and it should
prevent the static analyser to complain.
