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.
