Remove redundant setReserve call

Having two of the same call increases the chance of having
two .eh_frame entries for the same functionality.

Notice that setReserve took an int, and reserve used to take
a size_t. Every site where reserve() was used was actually
passing an int. So, I just unified the calls to take an int.
