[PATCH] target/arm: Add overflow check for gt_recalc_timer

If gt_timer is enabled before cval initialization on a virtualized setup on QEMU, cval equals (UINT64_MAX - 1). Adding an offset value to this causes an overflow that sets timer into the past, which leads to infinite loop, because this timer fires immediately and calls gt_recalc_timer() once more,
