Modified Files:
	src/sys/dev/wscons: wsdisplay.c

Log Message:
Do much more sanity checks when handling entries in the sc_scr array
of struct wsdisplay_softc. Unused entries are NULL, and there were
a lot of places where we did not checked that the caller did not
requested an operation on a NULL entry.

While we are there, one bit of KNFification, and make return code more
consistent by always returning the same code (EINVAL) when a screen
number higer than the maximum is requested.
