Commit 861a1a4d2 moved the qemuIsSharedHostdev filter in the
HOSTDEV half of the logic to allow calling qemuGetHostdevPath;
however, that neglected to check whether the SCSI hostdev was
using the iSCSI protocol which has a different overlayed struct
format (u.iscsi vs. u.host) resulting in attempted access of
u.host when calling virSCSIDeviceGetDevName.
