    bsdlabel: limit to 8 partitions

    bsdlabel is intended to support up to 20 partitions, but the disklabel
    struct has a d_partitions array with only BSD_NPARTS_MIN (8) entries.
    Previously, an attempt to operate on a bsdlabel with more than eight
    partitions resulted in a buffer overflow.

    As a stopgap limit bsdlabel to 8 partitions until this is fixed
    properly.
