mem_event: Return previous value of CR0/CR3/CR4 on change.

This patch extends the information returned for CR0/CR3/CR4 register
write events with the previous value of the register. The old value
was already passed to the trap processing function, just never placed
into the returned request. By returning this value, applications
subscribing the CR events obtain additional context about the event.
