The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.
milkymist_memcard_realize() is wrong that way: it passes &err to
qdev_prop_set_drive_err() and qdev_realize_and_unref(). Currently
harmless, because the latter uses it only as first argument of
error_propagate().
Making qdev_prop_set_drive_err() fail involves abuse of -global.
Leave handling that to qdev_prop_set_drive(), like we do elsewhere.
