Pass correct count to WALRead().
Previously, some callers requested XLOG_BLCKSZ bytes
unconditionally. While this did not cause a problem, because the extra
bytes are ignored, it's confusing and makes it harder to add safety
checks. Additionally, the comment about zero padding was incorrect.
With this commit, all callers request the number of bytes they
actually need.
