[PATCH] mkfs.xfs.8: Clarify mkfs vs. mount block size limits.

[Eric Sandeen]

The current explanation is a bit vague to the uninitiated;
clarify the text to make it obvious that while the mkfs.xfs
utility is able to create valid filesystems with block sizes
up to 65536, the Linux kernel can only mount filesystems with
page sized or smaller blocks.
