Rob Walker 70fbfa2cb8 winex11: Improve ChangeDisplaySettingsEx failed mode message. 
The failed mode error message dumps all the mode fields, that were
being tested. Change this output so that only the mode fields
explicitly being matched against are displayed.  Make the failed
message use formatting consist with the trace message, earlier in this
function.
