x-* prefix is used for userspace mount options and it's pretty commonly used to extend fstab configuration in systemd world (e.g. x-systemd.automount). These options is necessary to ignored. The command mount(8) does not pass x-* mount options to mount.<type> helpers, but in some use-cases it's possible that the cifs helper reads mount options from fstab or users directly call mount.cifs and copy & past mount options, etc. This patch marks all options prefixed by "x-" as OPT_IGNORE to make things more robust for end-users. We already uses the same concept for _netdev.
