    c/r: correctly restore retval for userspace tasks
    
    restore_retval() already fixes the return value when restarting tasks
    that were doing a syscall at the time of the checkpoint.
    
    The return value of restarting tasks that were frozen from userspace
    must also be loaded from the proper register (eax on x86) or else the
    latter will be overwritten.
    
    This fixes the consistent crashes seen on certain checkpoints that
    happen to be taken when the target process was in userspace, and its
    eax was not zero.
