parted: fix several integer overflows
Integer overflows were found in libparted/labels/dvh.c, while attemptting to assign unsigned int values to int types in some places. These overflows only can be observed on BE platforms like MIPS, when the "WORDS_BIGENDIAN" macro is defined in parted. Defined by unsigned int instead.
