[PATCH 5/5] fs: update kernel-doc for new mnt_userns argument

[Lukas Bulwahn]

Commit 549c7297717c ("fs: make helpers idmap mount aware") and commit
c7c7a1a18af4 ("xattr: handle idmapped mounts") refactor the inode methods
with mount-user-namespace arguments, but did not adjust the kernel-doc of
some functions.

Hence, make htmldocs warns:

  ./fs/libfs.c:498: warning: Function parameter or member 'mnt_userns' not described in 'simple_setattr'
  ./fs/xattr.c:257: warning: Function parameter or member 'mnt_userns' not described in '__vfs_setxattr_locked'
  ./fs/xattr.c:485: warning: Function parameter or member 'mnt_userns' not described in '__vfs_removexattr_locked'

Copy the existing kernel-doc description for that new argument from
__vfs_setxattr_noperm() to the other functions as well.
