During the O3PipeView execution, a potential invalid iterator is used to
Update the instruction storeTick field.

If the store_idx iterator is the first() of the StoreQueue, the
corresponding instruction is removed from the queue, leaving the iterator
invalid and not usable in the TRACING_ON block.

This patch uses the store_inst variable to access (and update) the
instruction tick, instead of the (potential) invalid one.
