nilfs2: fix duplicate call to nilfs_segctor_cancel_freev
Andreas Beckmann gave me a report that nilfs logged the following
warnings when it got a disk full:
nilfs_sufile_do_cancel_free: segment 0 must be clean
nilfs_sufile_do_cancel_free: segment 1 must be clean
These arise from a duplicate call to nilfs_segctor_cancel_freev in an
error path of log writer. This will fix the issue.
