virsh: don't print --(null) in vol-name and vol-pool

Browse Source 
Don't print the pool option name if it's null.

Before:
virsh # vol-name vol
error: failed to get vol 'vol', specifying --(null) might help
error: Storage volume not found: no storage vol with matching path vol

After:

virsh # vol-name vol
error: failed to get vol 'vol'
error: Storage volume not found: no storage vol with matching path vol
