TemplateTable::_new(): fix unaligned lw


InstanceKlass::init_state is defiend as "u2" and is assigned to 2-byte
boundary. Its offset is 0x16a.
Such field should be accessed with LHU.

public class List {
    public static void main(String[] args) {
        List th;
        while(true)
           th = new List();
    }
}


Effect:
* -Xmixed / -Xint: no unaligned instructions
