KVM: X86: Fix x86_emulator slab cache leak
Commit c9b8b07cded58 (KVM: x86: Dynamically allocate per-vCPU emulation context)
tries to allocate per-vCPU emulation context dynamically, however, the
x86_emulator slab cache is still exiting after the kvm module is unload
as below after destroying the VM and unloading the kvm module.
grep x86_emulator /proc/slabinfo
x86_emulator 36 36 2672 12 8 : tunables 0 0 0 : slabdata 3 3 0
This patch fixes this slab cache leak by destroying the x86_emulator slab cache
when the kvm module is unloaded.
