[GIT PULL] bcachefs fixes for 6.9

[Kent Overstreet]

Hi Linus, another stack of fixes for you.

Apologies for the size of the pull request, it's almost all syzbot stuff
which we just started receiving, and pretty much all simple validation
fixes. One user reported bugfix in here, a fix for an integer overflow
which was preventing returning the full list of extents to filefrag().

The following changes since commit c258c08add1cc8fa7719f112c5db36c08c507f1e:

  bcachefs: Add missing sched_annotate_sleep() in bch2_journal_flush_seq_async() (2024-05-06 23:12:09 -0400)

----------------------------------------------------------------
bcachefs fixes for 6.9

- Various syzbot fixes; mainly small gaps in validation
- Fix an integer overflow in fiemap() which was preventing filefrag from
  returning the full list of extents
- Fix a refcounting bug on the device refcount, turned up by new
  assertions in the development branch
- Fix a device removal/readd bug; write_super() was repeatedly dropping
  and retaking bch_dev->io_ref references
