perf tools: Fix a compiler warning of NULL pointer
A compiler warning on the second argument of bsearch() should not be
NULL, but there's a case we might pass it. Let's return early if we
don't have any DSOs to search in __dsos__find_by_longname_id().
util/dsos.c:184:8: runtime error: null pointer passed as argument 2, which is declared to never be null
