[PATCH v2 1/2] winex11.drv: optimise ChangeDisplaySettingsEx mode tests
Add pre-tests for the requested mode bpp and frequency. Fields: DM_PELSWIDTH , DM_PELSHEIGHT are re-tested in the testing loop multiple times. These fields must both be set and have already been tested before the loop.

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, used earlier in this function.
