Subject: perf auxtrace: Fix no_size logic in addr_filter__resolve_kernel_syms()

From: Adrian Hunter <adrian.hunter@intel.com>

commit c3a0bbc7ad7598dec5a204868bdf8a2b1b51df14 upstream.

Address filtering with kernel symbols incorrectly resulted in the error
"Cannot determine size of symbol" because the no_size logic was the wrong
way around.
