[libvirt] [PATCH 1/4] qemu: Tolerate storage source private data being NULL for hotplug SCSI hostdev
Commit id 'c5c96545' neglected to validate that the srcPriv was
non-NULL before dereferencing. Similar problem to what was fixed
by commit id '8056721c' but missed during multiple rebases and
code reworks.
