drop the f2fs block device release patch from 6.6

Dropped patches:

- "f2fs: move release of block devices to after kill_block_super()"
  Upstream: 275dca4630c1
  Queues: 6.6
  Reason: NACKed by Eric Biggers: not a clean cherry-pick, missing the
          follow-on fix, linux-f2fs-devel not Cc'd.
  Report: https://lore.kernel.org/stable/20261016173526.GB122880@google.com/

- "f2fs: quota: fix to avoid warning in dquot_writeback_dquots()"
  Upstream: eb85c2410d6f
  Queues: 6.6
  Reason: depends on the block device release patch dropped above
          (conflicts in fs/f2fs/super.c without it).
