[PATCH] ufs2 write: inodes write

This patch adds into write inode path function to write UFS2 inode, and
modifys allocate inode path to allocate and init additional inode chunks.

Also some cleanups:
- remove not used parameters in some functions
- remove i_gen field from ufs_inode_info structure,
there is i_generation in inode structure with same purposes.
