export: declare ksymtab symbols
sparse complains about any __ksymtab symbols with the following:
warning: symbol '__ksymtab_...' was not declared. Should it be static?
due to Andi's patch making it non-static.
Mollify sparse by declaring the symbol extern, otherwise we get
drowned in sparse warnings for anything that uses EXPORT_SYMBOL
in the sources, making it easy to miss real warnings.
Fixes: e0f244c63fc9 ("asmlinkage, module: Make ksymtab [...] __visible")
