perf tools: Add __data_loc support
This patch is required to test the next patch for perf lock.
At 064739bc4b3d7f424b2f25547e6611bcf0132415 ,
support for the modifier "__data_loc" of format is added.
But, when I wanted to parse format of lock_acquired (or some
event else), raw_field_ptr() did not returned correct pointer.
So I modified raw_field_ptr() like this patch. Then
raw_field_ptr() works well.
