Incorrect move to os.mkdir in Nexenta NFS and Quobyte Drivers

[Silvan Kaiser]

The recent Cinder change [1] moved shell mkdir commands to pythons os.mkdir commands. However as the shell commands were running with the '-p' option os.makedirs is required instead. Using os.mkdir results in failures as shown e.g. in the changes Quobyte CI run as the required mount point is not created correctly.
