This routine was checking only if the provided address was after sym->end, not if it was before sym->start. Fix that by checking for both and return in both cases -ERANGE, so that tools can communicate this to the user properly, or if they chose so, to abort. This problem was reported previously but the fixes involved either doing what was being done for the > end case, i.e. silently drop the sample, returning 0, or aborting at this function, which is in a lib (or better, is slated to be at some point) and shouldn't abort. The 'report' tool already checks this value and uses pr_debug to warn the user. This patch makes the 'top' tool check it too and warn once per map where such range problem takes place.
