With ztailpacking enabled, the current process assumes that a compacted_4b_end
always exists in the compacted pack. However, in some specific files, the
compacted pack may not have a compacted_4b_end. This leads to an incorrect
modification of the last compacted_2B entry, resulting in incorrect modification
of its clusterofs. In subsequent fsck operations, incorrect parameters will
affect the decompression of the penultimate pcluster.
This patch also handle the last compacted_2B pack correctly.
