target-s390x: fix PSW value on dynamical exception from helpers

Browse Source 
runtime_exception computes the psw.addr value using the actual exception
address and the instruction length computed by calling the get_ilen
function. However as explained above the get_ilen code, it returns the
actual instruction length, and not the ILC. Therefore there is no need to
multiply the value by 2.
