Rustam Kovhaev 19184bd06f KVM: fix memory leak in kvm_io_bus_unregister_dev()
[ Upstream commit f65886606c ]

when kmalloc() fails in kvm_io_bus_unregister_dev(), before removing
the bus, we should iterate over all other devices linked to it and call
kvm_iodevice_destructor() for them

Fixes: 90db10434b ("KVM: kvm_io_bus_unregister_dev() should never fail")
