[libvirt] [PATCH] conf: Add check for non scsi_host parent during vport delete

If the parent is not a scsi_host, then we can just happily return since
we won't be removing a vport.

Fixes a bug with the following output:

$ virsh pool-destroy host4_hba_pool
error: Failed to destroy pool host4_hba_pool
error: internal error: Invalid adapter name 'pci_0000_10_00_1' for SCSI pool
