nilfs2: get rid of back pointer to writable sb instance
Nilfs object holds a back pointer to a writable super block instance in nilfs->ns_writer, and this became eliminable since sb is now made per device and all inodes have a valid pointer to it. This deletes the ns_writer pointer and a reader/writer semaphore protecting it. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
