block: fix adding folio to bio
commit 26064d3e2b4d9a14df1072980e558c636fb023ea upstream.
>4GB folio is possible on some ARCHs, such as aarch64, 16GB hugepage
is supported, then 'offset' of folio can't be held in 'unsigned int',
cause warning in bio_add_folio_nofail() and IO failure.
Fix it by adjusting 'page' & trimming 'offset' so that `->bi_offset` won't
be overflow, and folio can be added to bio successfully.
Fixes: ed9832bc08db ("block: introduce folio awareness and add a bigger size from folio")

[ The follow-up fix fbecd731de05 ("xfs: fix zoned GC data corruption due to
wrong bv_offset") addresses issues in the file fs/xfs/xfs_zone_gc.c. This
file was first introduced in version v6.15-rc1. So don't backport the follow
up fix to 6.12.y. ]
