[PATCH 07/15] perf annotate: Fix storing per line sym_hist_entry

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

The existing loop incremented the offset while using it as the array
index, when we went to an array of sym_hist_entry instances, we
should've moved the increment to outside of the array element reference,
oops, fix it.
