Subject: [PATCH 28/38] perf symbols: Simplify out_fixup in kernel syms loading

From: Cody P Schafer <cody@...ux.vnet.ibm.com>

The only site that jumps to out_fixup has (kallsyms_filename == NULL).
And all paths that reach 'if (err > 0)' without 'goto out_fixup' have
kallsyms_filename != NULL.

So skip over both the check & dso__set_long_name(), and remove the
check.
