sysfs: fix sysfs root inode nlink accounting
While making sysfs indoes hashed, sysfs root inode was left out. Now
that nlink accounting depends on the inode being on the hash, sysfs
root inode nlink isn't adjusted properly.
Put sysfs root inode on the inode hash by allocating it using
sysfs_get_inode() like other sysfs inodes. While at it, massage
comments a bit.
