[PATCH v1 1/1] riscv: Pass RISCVHartArrayState by pointer

[Alistair Francis <alistair.francis@wdc.com>]

We were accidently passing RISCVHartArrayState by value instead of
pointer. The type is 824 bytes long so let's correct that and pass it by
pointer instead.

Fixes: Coverity CID 1438099
Fixes: Coverity CID 1438100
Fixes: Coverity CID 1438101
