Christoph Hellwig 2d29960af0 swiotlb: dynamically allocate io_tlb_default_mem
Instead of allocating ->list and ->orig_addr separately just do one
dynamic allocation for the actual io_tlb_mem structure.  This simplifies
a lot of the initialization code, and also allows to just check
io_tlb_default_mem to see if swiotlb is in use.
