[libvirt] [PATCH] util: fix libvirtd crash caused by virStorageNetHostTransportTypeFromString

[Shanzhi Yu]

When split uri->scheme into two strings with "+", the second one will be
"rdma://server/..", pass it to virStorageNetHostTransportTypeFromString
will lead libvirtd crash. So a second virStringSplit call is needed.
