ubik: ntohl on reading the replay log

When attempting to read the replay log, ubik was not ntohl'ing all
integers that were read in from the log, causing the log to appear
invalid on little-endian systems. Fix it.

This problem manifests as apparent corruption in the database on top
of ubik when a commit is occurring when we are shut down, or a disk
error is encountered during a commit.
