get rid of iterate_all_kinds() in iov_iter_get_pages()/iov_iter_get_pages_alloc()
Here iterate_all_kinds() is used just to find the first (non-empty, in
case of iovec) segment. Which can be easily done explicitly.
Note that in bvec case we now can get more than PAGE_SIZE worth of them,
in case when we have a compound page in bvec and a range that crosses
a subpage boundary. Older behaviour had been to stop on that boundary;
we used to get the right first page (for_each_bvec() took care of that),
but that was all we'd got.
