warnings: fix ".. may be used uninitialized in this function" warnings

Actually, it was already impossible for the reported variables to be
used uninitialized, because they were all assigned a value by calling
ReadByte() and the function would return if that failed. However, the
compiler couldn't know about this fact, so we do him the favor and
initialized them to 0.
