/proc/kcore: update stat.st_size after memory hotplug
After memory hotplug (or other events in future), kcore size can be modified. To update inode->i_size, we have to know inode/dentry but we can't get it from inside /proc directly. But considerinyg memory hotplug, kcore image is updated only when it's opened. Then, updating inode->i_size at open() is enough.
