  Hi,

a batch of error handling fixes for resource leaks, fixes for nowait
mode in combination with direct and buffered IO.  Please pull, thanks.

- direct IO + dsync + nowait could miss a sync of the file after write,
  add handling for this combination

- buffered IO + nowait should not fail with ENOSPC, only blocking IO
  could determine that

- error handling fixes
  - fix inode reserve space leak due to nowait buffered write
  - check the correct variable after allocation (direct IO submit)
  - fix inode list leak during backref walking
  - fix ulist freeing in self tests
