Dave Rigby 8d11e6ae43 perf unwind: Set userdata for all __report_module() paths
commit 4e1481445407b86a483616c4542ffdc810efb680 upstream.

When locating the DWARF module for a given address, __find_debuginfo()
requires a 'struct dso' passed via the userdata argument.

However, this field is only set in __report_module() if the module is
found in via dwfl_addrmodule(), not if it is found later via
dwfl_report_elf().

Set userdata irrespective of how the DWARF module was found, as long as
we found a module.
