StdLib/LibC/Uefi/Devices/Console/daConsole.c: Fix bug where unconvertable wide chara...

When the WideTtyCvt() function encountered an unconvertable character, it properly replaced it but did not update the byte count, numB, to 1 and instead left it at -1.

This fix sets numB to 1 when an unconvertable character is replaced.
