GPT partition entry array (GPEA) has 128 entries by default, unused ones
must be zeroed. Due to memory corruption GPEA contained non-zero data of
first sectors of partitions. This led to fake partitions detected which
were mostly filtered out by their start:length and thus didn't show up.
Pass ebx=three-sector-sized buffer to disk_add_partition as expected.
