nilfs2: change default of 'errors' mount option to 'remount-ro' mode
Like ext3, nilfs has 'errors' mount option to allow specifying desired
behavior on severe errors.
Currently, the default action is 'errors=continue' and has potential
to advance filesystem corruption for severe errors.
This will change the action to 'errors=remount-ro' to avoid the issue.
