Replace the open coded offset calculation with the proper helper.
This is an ABI change in that the -1 for a misaligned partition is
properly propagated, which can be considered a bug fix and matches
what is done on the whole device.

For block devices, the SCSI target drivers implements UNMAP as calls to

Write Zeroes is supported.
Note that this does not affect the file backed path which uses

Hi Jens,
this series cleanups up the block layer API so that APIs consumed
by file systems are (almost) only struct block_devic based, so that
file systems don't have to poke into block layer internals like the
request_queue.
I also found a bunch of existing bugs related to partition offsets
and
Hi Jens,
can you pull this into 5.19/block? I'd like to send some bio cloning

Add a helper to query the number of sectors support per each discard bio
based on the block device and use this helper to stop various places from
poking into the request_queue to see if discard is supported and if so how
much. This mirrors what is done e.g. for write zeroes as well.
Just use a non-zero max_discard_sectors as an indicator for discard
support, similar to what is done for write zeroes.
The only places where needs special attention is the RAID5 driver,
which must clear discard support for security reasons by default,
even if the default stacking rules would
Randomly poking into block device internals for manual prefetches isn't
exactly a very maintainable thing to do. And none of the performance
criticil direct I/O implementations still use this library function
anyway, so just drop it.
