  gfs2: Fix unlikely race in gdlm_put_lock (2025-09-12 12:03:01 +0200)

----------------------------------------------------------------
gfs2 changes

- Partially revert "gfs2: do_xmote fixes" to ignore dlm_lock() errors
  during withdraw; passing on those errors doesn't help.

- Change the LM_FLAG_TRY and LM_FLAG_TRY_1CB logic in add_to_queue() to
  check if the holder would actually block.

- Move some more dlm specific code from glock.c to lock_dlm.c.

- Remove the unused dlm alternate locking mode code.

- Add proper locking to make sure that dlm lockspaces are never used
  after being released.

- Various other cleanups.
