  fix warnings on 32bit caused by ITER_XARRAY fix (2022-06-11 12:43:21 -0400)

----------------------------------------------------------------
minimal fix for build breakage on 32bit
Signed-off-by: Al Viro <viro@...iv.linux.org.uk>

----------------------------------------------------------------
There's a bunch of obvious cleanups and improvements in that area; this is
just the braino fix for previous commit.  I wanted to include at least
replacement of weird open-coded count = DIV_ROUND_UP(size + offset, PAGE_SIZE);
in those two functions (it might have started as defense against theoretical
overflows, but if so it's incomplete, the overflows are in practice impossible
*and* this prevention would be in the wrong place anyway), but... let's
keep that separate.

FWIW, in my local tree duplication between iov_iter_get_pages() and
iov_iter_get_pages_alloc() is gone, with a lot of stuff getting considerably
simpler, but I'm still cleaning/reordering/carving that series up.  Will post
tomorrow or on Monday, but those are clearly not 5.19 fodder.
