[PATCH 05/10] perf symbols: Slightly simplify 'err' usage in dso__synthesize_plt_symbols()

[Adrian Hunter <adrian.hunter@intel.com>]

Return zero directly instead of needless 'goto out_elf_end' that does
the same thing. That allows 'err' to be initialized to -1 instead of
having to change its value later.
