xen_read_msr_safe() currently passes an uninitialized argument 'err' to xen_do_read_msr(). But as xen_do_read_msr() may not set the argument, xen_read_msr_safe() could return err with an unpredictable value. To ensure correctness, initialize err to 0 (representing success) in xen_read_msr_safe(). Do the same in xen_read_msr(), even err is not used after being passed to xen_do_read_msr().
