qemu_domain: Ignore all but SCSI hostdevs in qemuDomainDeviceHostdevDefPostParseRestoreBackendAlias()
When retiring QEMU_CAPS_BLOCKDEV_HOSTDEV_SCSI capability the
commit removed a bit too much. Previously, all other devices than
VIR_DOMAIN_HOSTDEV_SUBSYS_TYPE_SCSI were ignored in
qemuDomainDeviceHostdevDefPostParseRestoreBackendAlias(). But the
commit in question removed not only the capability check but also
this return early statement. Restore it back.
