Subject: [PATCH] scatterlist: remove ambiguous comment for public fields count of mapping iterator

The structure of SG mapping iterator have some public members, while its
comment text has invalid number of the fields, due to the extensions
added in later work.

This commit gives up to describe the count so that developers no longer
take extra care.

Fixes: 137d3edb4842 ("sg: reimplement sg mapping iterator")
Fixes: 4225fc8555a9 ("lib/scatterlist: use page iterator in the mapping iterator")
