[PATCH 6/8] nilfs2: describe the members of nilfs_bmap_operations structure

[Ryusuke Konishi <konishi.ryusuke@gmail.com>]

Add missing member variable descriptions in the kernel-doc comments
for the nilfs_bmap_operations structure, hiding the internal
operations with the "private:" tag.  This eliminates the following
warnings output by the kernel-doc script:

 fs/nilfs2/bmap.h:74: warning: Function parameter or struct member
  'bop_lookup' not described in 'nilfs_bmap_operations'
 fs/nilfs2/bmap.h:74: warning: Function parameter or struct member
  'bop_lookup_contig' not described in 'nilfs_bmap_operations'
 ...
 fs/nilfs2/bmap.h:74: warning: Function parameter or struct member
  'bop_gather_data' not described in 'nilfs_bmap_operations'
