nilfs2: add missing argument description for __nilfs_error()

Patch series "This series fixes a number of formatting issues in kernel
doc comments"


This series fixes a number of formatting issues in kernel doc comments
that were detected as warnings by the kernel-doc script, making violations
more noticeable when adding or modifying kernel doc.

There are still warnings output by "kernel-doc -Wall", but they are
widespread, so I plan to fix them at another time while considering
priorities.


This patch (of 8):

Add missing argument description to __nilfs_error function and remove the
following warnings from kernel-doc script output:

 fs/nilfs2/super.c:121: warning: Function parameter or struct member 'sb'
  not described in '__nilfs_error'
 fs/nilfs2/super.c:121: warning: Function parameter or struct member
  'function' not described in '__nilfs_error'
 fs/nilfs2/super.c:121: warning: Function parameter or struct member 'fmt'
  not described in '__nilfs_error'
