Commit 861a1a4d2 moved the qemuIsSharedHostdev filter in the
d76c62
HOSTDEV half of the logic to allow calling qemuGetHostdevPath;
d76c62
however, that neglected to check whether the SCSI hostdev was
d76c62
using the iSCSI protocol which has a different overlayed struct
d76c62
format (u.iscsi vs. u.host) resulting in attempted access of
d76c62
u.host when calling virSCSIDeviceGetDevName.
