Fix some Xr references:

- ada(4): ad(4) - removed, ada(4) would be a self-referencing entry
- cd(4): ad(4) -> ada(4)
- da(4): ad(4) -> ada(4)
- DEVICE_PROBE(9):  ugen(5) -> ugen(4)
- ed(4): dhclinet(8) -> dhclient(8) (typo)
- lmc(4): Netgraph(4) -> netgraph(4)
- security(7): rc.conf(8) -> rc.conf(5)
- sfxge(4): cpuset(8) -> cpuset(1)
- sbp(4): sysctl(1) -> sysctl(8)
- portindex(5): build(1) -> build(7)
- u3g(4): usbconfig(5) -> usbconfig(8)
- usb_quirk(4): usbconfig(5) -> usbconfig(8)
