When building qib_wc_x86_64.c on ARCH=um, references to some cpuinfo
fields cause build errors since cpuinfo does not contain x86-specific
fields.
Fix the build errors by making this driver depend on !UML.
Prevents these build errors:
../drivers/infiniband/hw/qib/qib_wc_x86_64.c: In function ‘qib_unordered_wc’:

You could argue that one might want to eventually use kunit for some
bits and pieces in there, so it'd make sense to be able to build the
parts that _can_ be built, but I have no idea :)

But now, we don't have anyone in RDMA who uses kunit. Once it will be
needed, he/she will extend drivers/infiniband to support it.

Ok, to be more pedantic "none of RDMA HW code ...".
However does anybody use rxe or siw in UML?
