[PATCH -next] nilfs2: Fix typos in comments

[Lu Jialin <lujialin4-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>]

numer -> number in fs/nilfs2/cpfile.c and fs/nilfs2/segment.c
retured -> returned and Decription -> Description in fs/nilfs2/ioctl.c
isntance -> instance in fs/nilfs2/the_nilfs.c
No functionality changed.
