[PATCH 3/3] ubifs: ubifs.h: clean up kernel-doc comments

- use the struct keyword when describing a struct in kernel-doc format.
- add or correct missing struct members @leaf, @eof, and
  @superblock_need_write.
- add Returns: clauses for 4 function descriptions.

to prevent kernel-doc warnings:

Warning: fs/ubifs/ubifs.h:755 struct member 'leaf' not described in 'ubifs_zbranch'
Warning: fs/ubifs/ubifs.h:814 struct member 'eof' not described in 'bu_info'
Warning: fs/ubifs/ubifs.h:814 Excess struct member 'oef' description in 'bu_info'
Warning: fs/ubifs/ubifs.h:992 cannot understand function prototype: 'struct ubifs_stats_info'
Warning: fs/ubifs/ubifs.h:1513 struct member 'superblock_need_write' not described in 'ubifs_info'
Warning: fs/ubifs/ubifs.h:1597 No description found for return value of 'ubifs_check_hash'
Warning: fs/ubifs/ubifs.h:1612 No description found for return value of 'ubifs_check_hmac'
Warning: fs/ubifs/ubifs.h:1653 No description found for return value of 'ubifs_branch_hash'
Warning: fs/ubifs/ubifs.h:1703 No description found for return value of 'ubifs_auth_node_sz'
