[PATCH 2/2] MdePkg/UefiDebugLibStdErr: Pass the correct buffer size.

["Marvin Häuser" <Marvin.Haeuser@outlook.com>]

The second argument of "UnicodeVSPrintAsciiFormat" is "BufferSize",
which takes the size of the buffer in bytes. Replace the currently
used MAX_DEBUG_MESSAGE_LENGTH reference, which is the buffer's length,
with the actual buffer size.
