FROMLIST: export: fix string handling of namespace in EXPORT_SYMBOL_NS

Browse Source 
Commit c3a6cf19e6 ("export: avoid code duplication in
include/linux/export.h") broke the ability for a defined string to be
used as a namespace value.  Fix this up by adding another layer of
indirection to preserve the previous functionality.
