KVM: arm64: Fully zero the vcpu state on reset
On vcpu reset, we expect all the registers to be brought back
to their initial state, which happens to be a bunch of zeroes.
However, some recent commit broke this, and is now leaving a bunch
of registers (such as the FP state) with whatever was left by the
guest. My bad.
Zero the reset of the state (32bit SPSRs and FPSIMD state).
