riscv: KVM: Fix SBI TIME error generation

Browse Source 
[ Upstream commit b901484852992cf3d162a5eab72251cc813ca624 ]

When an invalid function ID of an SBI extension is used we should
return not-supported, not invalid-param.

Fixes: 5f862df558 ("RISC-V: KVM: Add v0.1 replacement SBI extensions defined in v0.2")
