Title: Allow volume in error status to be deleted.

delete_volume_when_available was stalling unnecessarily when the volume is in error status. The method polls till the volume becomes available again, and there is a timeout associated with the polling. For large no of volumes in error state, waiting till the poll timeout is expensive. And hence the extra check to allow a volume to be deleted when it is in error status.
