[PATCH v2 2/4] perf symbol: Add missing symsrc__destroy() for libbfd

[Namhyung Kim <namhyung@kernel.org>]

When libbfd loaded symbols and there's a pending syms_ss, it'd be lost
or overwrite existing symbols.  Let's destroy it before breaking the
loop so that it can safely return from the function.

Closes: https://lore.kernel.org/r/sashiko-outbox-162540@kernel.org
Fixes: eac9a4342e5447cad ("perf symbols: Try reading the symbol table with libbfd")
