Robin Murphy 4e43ae1055 swiotlb: fail map correctly with failed io_tlb_default_mem ...

[ Upstream commit c51ba246cb172c9e947dc6fb8868a1eaf0b2a913 ]

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: 463e862ac63e ("swiotlb: Convert io_default_tlb_mem to static allocation")
