Chenggang	faa34a0738	platform/kvm: Get max vcpu number dynamically by ioctl The old kernel version, such as 4.4, only support 255 vcpus. While gvisor is ran on these kernels, it could panic because the vcpu id and vcpu number beyond max_vcpus. Use ioctl(vmfd, _KVM_CHECK_EXTENSION, _KVM_CAP_MAX_VCPUS) to get max vcpus number dynamically.

platform/kvm: Get max vcpu number dynamically by ioctl

The old kernel version, such as 4.4, only support 255 vcpus.
While gvisor is ran on these kernels, it could panic because the
vcpu id and vcpu number beyond max_vcpus.
Use ioctl(vmfd, _KVM_CHECK_EXTENSION, _KVM_CAP_MAX_VCPUS) to get max
vcpus number dynamically.
