nilfs2: eliminate sparse warning - "context imbalance"
insert sparse annotations to fix following sparse warning. fs/nilfs2/segment.c:2681:3: warning: context imbalance in 'nilfs_segctor_kill_thread' - unexpected unlock nilfs_segctor_kill_thread is only called inside sc_state_lock lock. sparse doesn't detect the context and warn "unexpected unlock". __acquires/__releases pretend to lock/unlock the sc_state_lock for sparse.
