SMBFS: provisioning type not honored

[Lucian Petrut]

At the moment, the SMBFS driver does not honor the configured provisioning type.

The issue is that we're checking CONF.backend_defaults instead of the driver configuration object, for which reason if the option is defined in the according backend config group, it will be ignored.

So, the following will work:

[backend_defaults]
nas_volume_provisioning_type = thick

While the following will not:

[DEFAULT]
enabled_backends = winsmb

[winsmb]
volume_driver = cinder.volume.drivers.windows.smbfs.WindowsSmbfsDriver
nas_volume_provisioning_type = thick

    [Trivial] SMBFS: fix provisioning type usage

    At the moment, the SMBFS driver does not honor the configured
    provisioning type.

    The issue is that we're checking CONF.backend_defaults instead
    of the driver configuration object, for which reason if the option
    is defined in the according backend config group, it will be ignored.

    This change fixes this issue, updating the config option checks.
