Vincent Donnefort 1702da76e0 KVM: arm64: Fix nVHE/pKVM hyp tracing error on invalid desc ... pKVM must validate the host-provided tracing buffer descriptor. However, if an error is found, the hypervisor would just return 0 to the host. Fix the return value on validation failure. While at it, rename the function to hyp_trace_desc_is_valid() and skip validation for the nVHE mode as we trust host-provided data in that case.
