hosting_platform.module doesn't support database prefix

Very small bug with a very simple fix.

Line 200 of platform/hosting_platform.module doesn't use curly braces around the database names:

$iid = db_result(db_query("SELECT iid FROM hosting_package_instance i left join hosting_package p on p.nid=i.package_id WHERE p.package_type='platform' AND i.rid=%d", $node->nid));

Should be:

$iid = db_result(db_query("SELECT iid FROM {hosting_package_instance} i left join {hosting_package} p on p.nid=i.package_id WHERE p.package_type='platform' AND i.rid=%d", $node->nid));

Patch attached.
