Subject: [PATCH 07/41] perf tools: Fix missing kernel map load

thread__find_addr_map() falls back to trying
the kernel maps if the address is negative and
is not found in userspace maps.  As commented
in the code, the kernel maps must be "loaded"
before use.  This patch ensures that happens
under the fallback condition also.
