[PATCH 2/2] perf symbols: Use the right variable to check for kallsyms in the cache

[Arnaldo Carvalho de Melo <acme@infradead.org>]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Probably this wasn't noticed when testing this on my parisc machine
because I must have copied manually to its cache the vmlinux file used
in the x86_64 machine, now that I tried looking on a x86-32 machine with
a fresh cache, kernel symbols weren't being resolved even with the right
kallsyms copy on its cache, duh.
