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.
