[sheepdog] [Patch]Sheepdog storage driver ignore refreshVol func's return value

[harryxiyou]

Hi all,

In libvirt/src/storage/storage_backend_sheepdog.c file, func
virStorageBackendSheepdogCreateVol calls func
virStorageBackendSheepdogRefreshVol to refresh Sheepdog volume infos.
But we do not check func virStorageBackendSheepdogRefreshVol's return
value. Following patch can fix this bug.
