virt: vbox: Sanity-check parameter types for hgcm-calls coming from userspace
Userspace can make host function calls, called hgcm-calls through the
/dev/vboxguest device.
In this case we should not accept all hgcm-function-parameter-types, some
are only valid for in kernel calls.
This commit adds proper hgcm-function-parameter-type validation to the
ioctl for doing a hgcm-call from userspace.
