[PATCH 3/3] Hardware iSCSI support

Currently we retrieve all the necessary information of an iSCSI session and pass them to 2nd kernel. This is wrong way to go for hardware iscsi, because dracut has already had its own infrastructure to do bring up any iscsi device configured in firmware of an HBA (Host Bus Bridge). This patch will determine if an iscsi session is established by firmware configured iscsi. If it does, then we don't pass anything down to 2nd kernel. dracut will handle it.
