svn commit: r222111 - projects/bhyve/sys/amd64/vmm/intel

New Revision: 222111

Log:
  Avoid unnecessary sign extension when promoted to a 64-bit integer.
  
  This was benign because the interruption info field is a 32-bit quantity and
  the hardware guarantees that the upper 32-bits are all zeros. But it did make
  reading the objdump output very confusing.
