iscsi_ibft: Add prefix-len attr and display netmask
The iBFT table only specifies a prefix length, not a netmask.
And the netmask is pretty much pointless for IPv6.
So introduce a new attribute 'prefix-len'.
Some older user-space code might rely on the netmask attribute
being present, so we should always display it.
Changes from v1:
- Combined two patches into one
Changes from v2:
- Cleaned up/corrected wording for patch description
