eh.  If there's a module anywhere which calls swiotlb_init() then I suspect
it's one which deserves breaking ;)

I'll remove the export.

 This warning happens because the function 
 swiotlb_init is marked __init and EXPORT_SYMBOL().
 A 'git grep swiotlb_init' showed no users in drivers/
 so maybe the EXPORT_SYMBOL can be deleted which would cure the warning?
 
 I took the pragmatic approach and made it non-__init.
