Ryusuke Konishi 090fd5b101 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.
