xfs_bmap: fix -n documentation in manpage

xfs_bmap's manpage mis-describes the behavior of the
-n option.  xfs_io's fiemap command references the xfs_bmap
manpage, and has the same problem:

-n does not change the query batch size, it limits the number
of extents displayed.

This has been true for 15+ years, so change the documentation
to match reality.
