[PATCH] KVM: arm64: cancel the return value check of kvm_arm_init_sve()

[Peng Wu <wupeng58@huawei.com>]

Currently, kvm_arm_init_sve() has only a unique return value,
so change the return value type of kvm_arm_init_sve() to void.

Meanwhile, there's no need to check the return value of
kvm_arm_init_sve() in kvm_arch_init().
