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.
