xfs: revert commit 8954c44ff477

The name passed into __xfs_xattr_put_listent is exactly namelen bytes
long and not null-terminated.  Passing namelen+1 to the strscpy function

    strscpy(offset, (char *)name, namelen + 1);

is therefore wrong.  Go back to the old code, which works fine because
strncpy won't find a null in @name and stops after namelen bytes.  It
really could be a memcpy call, but it worked for years.
