KVM: x86: Fully re-initialize supported_vm_types on vendor module load
Recompute the entire set of supported VM types when a vendor module is
loaded, as preserving supported_vm_types across vendor module unload and
reload can result in VM types being incorrectly treated as supported.
E.g. if a vendor module is loaded with TDP enabled, unloaded, and then
reloaded with TDP disabled, KVM_X86_SW_PROTECTED_VM will be incorrectly
retained. Ditto for SEV_VM and SEV_ES_VM and their respective module
params in kvm-amd.ko.
