conf: fix cannot start a guest have a shareable network iscsi hostdev
https://bugzilla.redhat.com/show_bug.cgi?id=1174569

steps:
1. discover a iscsi lun disk
# iscsiadm --mode discovery --type sendtargets --portal 10.xx.yy.zz (ip hidden)
10.xx.yy.zz:3260,1 www.lento.com:sunyi1
2. start a vm with above iscsi disk
<hostdev mode='subsystem' type='scsi' managed='no'>
<source protocol='iscsi' name='www.lento.com:sunyi1/1'>
<host name='10.xx.yy.zz' port='3260'/>
</source>
<readonly/>
<shareable/>
<alias name='hostdev0'/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</hostdev>
# virsh start rhel7.0
Domain rhel7.0 started
3. in guest os, check the iscsi disk really attached.
root@guest # fdisk -l
