[PATCH v2] infiniband: disable IB HW for UML

[Randy Dunlap <rdunlap@infradead.org>]

Disable all of drivers/infiniband/hw/ for UML builds until someone
needs it and provides patches to support it.

This prevents build errors in hw/qib/qib_wc_x86_64.c.

Fixes: 68f5d3f3b654 ("um: add PCI over virtio emulation driver")
