KVM: arm/arm64: vgic: Fix kvm_device leak in vgic_its_destroy
[ Upstream commit 4729ec8c1e1145234aeeebad5d96d77f4ccbb00a ]
kvm_device->destroy() seems to be supposed to free its kvm_device
struct, but vgic_its_destroy() is not currently doing this,
resulting in a memory leak, resulting in kmemleak reports such as
the following:
unreferenced object 0xffff800aeddfe280 (size 128):
comm "qemu-system-aar", pid 13799, jiffies 4299827317 (age 1569.844s)
[...]
backtrace:
[<00000000a08b80e2>] kmem_cache_alloc+0x178/0x208
[<00000000dcad2bd3>] kvm_vm_ioctl+0x350/0xbc0
Fix it.
