nilfs2: get rid of s_dirt flag use
This replaces s_dirt flag use in nilfs with a new flag added on the
nilfs object. The s_dirt flag was used to indicate if
sop->write_super() should be called, however the current version of
nilfs does not use the callback. Thus, it can be replaced with the
own flag.
