perf symbols: Load kernel maps before using
In order to use kernel maps to read object code, those maps must be
adjusted to map to the dso file offset. Because lazy-initialization is
used, that is not done until symbols are loaded. However the maps are
first used by thread__find_addr_map() before symbols are loaded. So
this patch changes thread__find_addr() to "load" kernel maps before
using them.
