Robin Murphy ee3bce3554 UPSTREAM: swiotlb: fail map correctly with failed io_tlb_default_mem ...

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.

Bug: 254441685
Fixes: 463e862ac6 ("swiotlb: Convert io_default_tlb_mem to static allocation")
