nbd: Fix interpretation of the export flags
The export flags are a 16 bit value, so be16_to_cpu() has to be used to interpret them correctly. This makes discard and flush actually work for named NBD exports (they did not work before, because the client always assumed them to be unsupported because of the bug fixed by this patch).
