[Bug 219913] emulators/virtualbox-ose-kmod: if the MAXCPU option is not the default for the running kernel, then 'kldload vboxdrv.ko' will result in a kernel panic

--- Comment #16 from Vladimir Druzenko <vvd@FreeBSD.org> ---
So, we have come to the conclusion that now (MAXCPU=1024 by default) there is
very little point in creating any patch for emulators/virtualbox-ose-kmod?
Therefore, I propose to simply close this PR as an Overcome by Events.

IMHO, we should think about the next increase MAXCPU before release 15:
- Intel has had CPU [1] for over a year now that allow to create a server with
960 threads (60 cores per socket * 2 threads per core * 8 sockets);
- AMD just announced [2] a CPU with 192 cores per socket * 2 threads per core *
2 sockets = 768 threads.
So even before the end of life of 14, servers with the number of threads > 1024
may appear.
