KVM: riscv: Fix Spectre-v1 in AIA CSR access
User-controlled indices are used to access AIA CSR registers.
Sanitize them with array_index_nospec() to prevent speculative
out-of-bounds access.
Similar to x86 commit 8c86405f606c ("KVM: x86: Protect
ioapic_read_indirect() from Spectre-v1/L1TF attacks") and arm64
commit 41b87599c743 ("KVM: arm/arm64: vgic: fix possible spectre-v1
in vgic_get_irq()").
