Zongmin Zhou 8d9c9b135b KVM: riscv: Fix Spectre-v1 in vector register access ...

User-controlled register indices from the ONE_REG ioctl are used to
index into the vector register buffer (v0..v31). Sanitize the calculated
offset with array_index_nospec() to prevent speculative out-of-bounds
access.
