mkfs.ubifs: Fix xattr nlink value
The nlink value of a xattr node must always be one, it has nothing to do
with the nlink value of the inode the attribute belongs to.
The bug can be observed when mounting a mkfs.ubifs generated image which
contains xattrs on directories or files with hardlinks to them. When
mounting such an image with chk_fs = 1 it fails with:
UBIFS error (ubi0:0 pid 1833): dbg_check_filesystem: inode 3308 nlink is 3, but calculated nlink is 1
Another bug that can be triggered is an assertion in
ubifs_xattr_remove() which assures that the xattr i_nlink count should
be one when the xattr is removed.
Fixes: 50044ef ("mkfs.ubifs: Add extended attribute support")
