Fix LinkInodeInDir return value.

Browse source 
The callers expected it to return an int different than 0 on failure. The
link method returns different than 0 on failure. This actually worked by
lucky coincidence. Change the return type to int and 0 on success, and -1
on failure per popular demand.

Thanks to Meisaka Yukara for spotting this.
