[PATCH 3/5] esx: split targetToStoragePool helper

[Pino Toscano <ptoscano@xxxxxxxxxx>]

Move the creation of a virStoragePtr object from the
esxVI_HostInternetScsiHbaStaticTarget object of a target out of
esxStoragePoolLookupByName in an own helper. This way it can be used
also in other functions.
