module: Convert default symbol namespace to string literal

Browse Source 
Commit cdd30ebb1b ("module: Convert symbol namespace to string
literal") only converted MODULE_IMPORT_NS() and EXPORT_SYMBOL_NS(),
leaving DEFAULT_SYMBOL_NAMESPACE as a macro expansion.

This commit converts DEFAULT_SYMBOL_NAMESPACE in the same way to avoid
annoyance for the default namespace as well.

Questo va messo prima di un qualsiasi uso di EXPORT_SYMBOL.

子系统的 ``Makefile`` 中定义默认命名空间。例如，如果要将usb-common中定义的所有符号导
出到USB_COMMON命名空间，可以在drivers/usb/common/Makefile中添加这样一行::
ccflags-y += -DDEFAULT_SYMBOL_NAMESPACE=USB_COMMON
ccflags-y += -DDEFAULT_SYMBOL_NAMESPACE='"USB_COMMON"'

用EXPORT_SYMBOL_NS()导出的符号仍然会被导出到作为命名空间参数传递的命名空间中，
