cpu-o3: Reset fault status for mem access in pushRequest

Reset the fault status always before translation is initiated in
pushRequest() in the LSQ. This avoids the problem when a strictly
ordered load needs to be re-executed multiple times. If the
translation is delayed at one of those attempts then the
internal panicFault (from the previous execution attempt) can get
fired at commit.
