[PATCH] perf callchain: Pass relative address to hist entry

[Namhyung Kim <namhyung@kernel.org>]

The addr_location->addr should have relative address to be passed to
hist entry so that it can compare with others which might come from a
different address space.

The callchain_cursor_node->ip already has a relative address thus it
should not map it again.  But I found a bug handling cumulative
(children) entries.  For chilren entries that has no self period, the
al->addr (so he->ip) ends up having an doubly-mapped address.

It seems to be there from the beginning but only affects entries that
have no srclines - finding srcline itself is done using a different
address but it will show the invalid address if no srcline was found.
