[PATCH] docs: fix INTRODUCE description in xenstore.txt

[Juergen Gross <jgross@xxxxxxxx>]

The description of the Xenstore INTRODUCE command is still referencing
xend. Fix that.

While at it, make clear that the Xenstore implementation is allowed
to ignore the specified gfn and use the Xenstore reserved grant id
GNTTAB_RESERVED_XENSTORE instead.
