Code cleanup: o_ptr->pval still used for rods in some places

[Zaxx]

Since now rods use o_ptr->timeout and k_ptr->time to handle activation, the occurences of o_ptr->pval should be removed/replaced.

In object_absorb():
o_ptr->pval = total * j_ptr->pval; (remove)

In inven_damage():
o_ptr->pval -= o_ptr->pval * amt / o_ptr->number; (bug: need to use reduce_charges instead)

In wiz_quantity_item():
o_ptr->pval = (o_ptr->pval / o_ptr->number) * tmp_int; (same problem)

In store_object_similar():
check (o_ptr->tval != TV_ROD) on pval (remove)

[Zaxx]

In store_object_absorb(): no need to add the timeouts for rods since they are automatically recharged (see store_carry).

I'll take this - thanks for the analysis.
