[PATCH] hugetlbfs: correct obsolete function name hugetlbfs_read_iter()

[Miaohe Lin]

The func do_generic_mapping_read() is killed by commit 36e789144267 ("kill
do_generic_mapping_read"). So replace it with do_generic_mapping_read to
keep comment uptodate.

Many thanks for your review. I'am going to resend this patch as I forgot to mention the
second commit that rename do_generic_file_read to generic_file_buffered_read. But it looks
I should send a v2 now to fix above comment.

Thanks again.
