perf tools: Do not disable source line lookup just because of 1 failure
Looking up an ip's source file name and line number does not succeed always. Current logic disables the lookup for a dso entirely on any failure. Change it so that disabling never happens if there has ever been a successful lookup for that dso but disable if the first 123 lookups fail.
