Subject: [PATCH 1/2 v2] IB/qib: don't use qib_wc_x86_64 for UML

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’:
../drivers/infiniband/hw/qib/qib_wc_x86_64.c:149:29: error: ‘struct cpuinfo_um’ has no member named ‘x86_vendor’
  149 |         return boot_cpu_data.x86_vendor != X86_VENDOR_AMD;
../drivers/infiniband/hw/qib/qib_wc_x86_64.c:149:44: error: ‘X86_VENDOR_AMD’ undeclared (first use in this function); did you mean ‘X86_VENDOR_ANY’?
  149 |         return boot_cpu_data.x86_vendor != X86_VENDOR_AMD;
../drivers/infiniband/hw/qib/qib_wc_x86_64.c:149:44: note: each undeclared identifier is reported only once for each function it appears in
../drivers/infiniband/hw/qib/qib_wc_x86_64.c:150:1: error: control reaches end of non-void function [-Werror=return-type]
  150 | }
