KVM: arm64: Fix misuse of KVM_ARM_VCPU_POWER_OFF bit index

Browse source

KVM_ARM_VCPU_POWER_OFF is as bit index, _not_ a literal bitmask.
Nonetheless, commit e3c1c0cae3 ("KVM: arm64: Relax invariance
of KVM_ARM_VCPU_POWER_OFF") started using it that way, meaning that
powering off a vCPU with the KVM_ARM_VCPU_INIT ioctl is completely
broken.

Fix it by using a shifted bit for the bitwise operations instead.
