Fix bhyve type19 SMBIOS handling to avoid losing 4GB

[bcran]

This fixes the amount of memory displayed in the UiApp to be the same as passed on the bhyve command line. Otherwise, 8GB gets displayed as 4, 32GB as 28 etc.

Isnt this tied to the xsaddr setting in the preceding line, such that this should more correctly be written:

type19->xeaddr = guest_himem + type19->xsaddr;

Perhaps, though that's relatively minor (and it won't ever move). The other nitpick one could observe is to perhaps order it as 'start + size' instead of 'size + start', i.e. xsaddr + guest_himem, but any of the variants is fine with me TBH.

I agree, @rgrimes - I'll fix it to be type19->xsaddr + guest_himem;
