Subject: [PATCH 2/3] perf tools: Fix usage of the verbose variable
The data type of the verbose variable is integer and can be negative,
replace improperly used cases in a unified manner:
1. if (verbose) => if (verbose > 0)
2. if (!verbose) => if (verbose <= 0)
3. if (XX && verbose) => if (XX && verbose > 0)
4. if (XX && !verbose) => if (XX && verbose <= 0)
