Incorrect comment of XLByteToSeg() and XLByteToPrevSeg()

Hi,

I found a type in the comment for XLByteToSeg() and XLByteToPrevSeg().
This says "Compute ID and segment from an XLogRecPtr", but these
macros compute only segment numbers. I think "Compute a segment number
from an XLogRecPtr" is correct.

The definition of these macros were modified by the following commit,
but the comment were not.
