ipfs init is not reporting failures

[Luzifer]

Given the $IPFS_PATH is not writable for ipfs init the command does show the output we're used to as if it worked fine. Instead it should show an fatal error because ipfs init is in fact not able to write into that directory and it is empty afterwards which causes strange errors:

# echo $IPFS_PATH
/data/ipfs

# ls -lhR /data
/data:
total 4.0K
drwxr-xr-x 2 root root 4.0K Apr 23 20:58 ipfs

/data/ipfs:

Good catch, should be a moderately easy fix in cmd/ipfs/init.go or maybe somewhere in repo/fsrepo.
