iohyve disks incorrectly showing

[the-vty]

Hi pr1ntf,

Thanks for excellent tool!
I noticed that "iohyve disks" displays wrong info if a vm name is used matches with other vms:

# iohyve list
Guest       VMM?  Running  rcboot?  Description
debian      YES   YES      YES      Thu May 10 13:59:08 CEST 2018
debian.old  NO    NO       NO       Sun Oct 16 18:47:12 CEST 2016
ubuntu      NO    NO       NO       Wed May  9 15:11:30 CEST 2018

# iohyve disks debian
Listing  disks  for  debian...
diskN    Size
disk0    60G
disk0    20G
disk1    40G

The first "disk0" is taken from debian.old because the regexp in ioh-disk matches both "debian" and "debian.old"
The easiest fix would be to change
zfs list -H -o name,volsize | grep -E "iohyve.*$name.*disk"
to:
zfs list -H -o name,volsize | grep -E "iohyve.*$name/disk"

# zfs list -H -o name,volsize | grep -E 'iohyve.*debian/disk'
zroot/iohyve/debian/disk0	20G
zroot/iohyve/debian/disk1	40G
