[PATCH V7 2/7] perf tools: fix annotate_browser__callq()

[Adrian Hunter <adrian.hunter@intel.com>]

When following a call, annotate_browser__callq()
uses the current symbol's map to look up the
target ip.  That will not work if the target ip
is on a map with a different mapping (i.e.
start - pgoff is different).
