NetApp: Define 'preferred' to False instead of none

Define preferred to false instead of none in the NetApp driver
as setting it to none will trigger a traceback later on because
the database doesn't allow null values to be inserted.
"preferred" export location metadata must be set to true or
false.  warning logging is also added to the SQLAlchemy API
if a none value is used to update the export location metadata.

Fixed the NetApp driver to report the correct value of the "preferred"
export location metadata where it cannot determine if there are any
"preferred" export locations.
