Subject: [PATCH] nilfs2: add nilfs_sufile_set_suinfo to update segment usage

Introduce nilfs_sufile_set_suinfo(), which expects an array of
nilfs_suinfo_update structures and updates the segment usage information
accordingly.

This is basically a helper function for the newly introduced
NILFS_IOCTL_SET_SUINFO ioctl.
