KVM: remove deprecated UAPIs

The deprecated interfaces were removed 15 years ago.  KVM's
device assignment was deprecated in 4.2 and removed 6.5 years
ago; the only interest might be in compiling ancient versions
of QEMU, but QEMU has been using its own imported copy of the
kernel headers since June 2011.  So again we go into archaeology
territory; just remove the cruft.
