When we hit an UE while using machine check safe copy routines,

on checking if the effective address is provided or physical address
is calculated, which is not right.
Save ignore_event flag regardless of whether the effective address is
provided or physical address is calculated.
Without this change following log is seen, when the event is to be
ignored.
