Robin Murphy 1008e81163 swiotlb: fail map correctly with failed io_tlb_default_mem ...

[ Upstream commit c51ba246cb ]

In the failure case of trying to use a buffer which we'd previously
failed to allocate, the "!mem" condition is no longer sufficient since
io_tlb_default_mem became static and assigned by default. Update the
condition to work as intended per the rest of that conversion.

Fixes: 463e862ac6 ("swiotlb: Convert io_default_tlb_mem to static allocation")
