KVM: arm64: Initialize the kvm host data's fpsimd_state pointer in pKVM

Browse source

Since the host_fpsimd_state has been removed from kvm_vcpu_arch,
it isn't pointing to the hyp's version of the host fp_regs in
protected mode.

Initialize the host_data fpsimd_state point to the host_data's
context fp_regs on pKVM initialization.
