nilfs2: fix inconsistencies in kernel-doc comments in segment.h

Fix incorrect or missing variable names in the member variable
descriptions in the nilfs_recovery_info and nilfs_sc_info structures,
thereby eliminating the following warnings output by the kernel-doc
script:

 fs/nilfs2/segment.h:49: warning: Function parameter or struct member
  'ri_cno' not described in 'nilfs_recovery_info'
 fs/nilfs2/segment.h:49: warning: Function parameter or struct member
  'ri_lsegs_start_seq' not described in 'nilfs_recovery_info'
 fs/nilfs2/segment.h:49: warning: Excess struct member 'ri_ri_cno'
  description in 'nilfs_recovery_info'
 fs/nilfs2/segment.h:49: warning: Excess struct member 'ri_lseg_start_seq'
  description in 'nilfs_recovery_info'
 fs/nilfs2/segment.h:177: warning: Function parameter or struct member
  'sc_seq_accepted' not described in 'nilfs_sc_info'
 fs/nilfs2/segment.h:177: warning: Function parameter or struct member
  'sc_timer_task' not described in 'nilfs_sc_info'
 fs/nilfs2/segment.h:177: warning: Excess struct member 'sc_seq_accept'
