block: Fix bvec_set_folio() for very large folios
[ Upstream commit 5e223e06ee7c6d8f630041a0645ac90e39a42cc6 ]
Similarly to 26064d3e2b4d ("block: fix adding folio to bio"), if
we attempt to add a folio that is larger than 4GB, we'll silently
truncate the offset and len. Widen the parameters to size_t, assert
that the length is less than 4GB and set the first page that contains
the interesting data rather than the first page of the folio.
Fixes: 26db5ee15851 (block: add a bvec_set_folio helper)
