netfs: Add a function to extract an iterator into a scatterlist
Provide a function for filling in a scatterlist from the list of pages
contained in an iterator.
If the iterator is UBUF- or IOBUF-type, the pages have a pin taken on them
(as FOLL_PIN).
If the iterator is BVEC-, KVEC- or XARRAY-type, no pin is taken on the
pages and it is left to the caller to manage their lifetime. It cannot be
assumed that a ref can be validly taken, particularly in the case of a KVEC
iterator.

netfs: Fix dodgy maths
Fix the dodgy maths in netfs_rreq_unlock_folios(). start_page could be
inside the folio, in which case the calculation of pgpos will be come up
with a negative number (though for the moment rreq->start is rounded down
earlier and folios would have to get merged whilst locked)
Alter how this works to just frame the tracking in terms of absolute file
positions, rather than offsets from the start of the I/O request. This
simplifies the maths and makes it easier to follow.
Fix the issue by using folio_pos() and folio_size() to calculate the end
position of the page.

netfs: Rename the netfs_io_request cleanup op and give it an op pointer
The netfs_io_request cleanup op is now always in a position to be given a
pointer to a netfs_io_request struct, so this can be passed in instead of
the mapping and private data arguments (both of which are included in the
struct).
So rename the ->cleanup op to ->free_request (to match ->init_request) and
pass in the I/O pointer.
