doc: module: DEFAULT_SYMBOL_NAMESPACE must be defined before #includes
The definition of EXPORT_SYMBOL et al depends on
DEFAULT_SYMBOL_NAMESPACE. So DEFAULT_SYMBOL_NAMESPACE must already be
available when <linux/export.h> is parsed.
Also when defined that early there is no need for an #undef, so drop
that from the usage example.
