Log Message:
-----------
StdLib/LibC/Uefi/Devices/Console/daConsole.c: Fix bug where unconvertable wide
characters would cause the code to hang or generate an exception.
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.
