target/riscv/csr.c: use riscv_cpu_cfg() to avoid env_cpu() pointers

A common trend in this file is to retrieve a RISCVCPU pointer by first
retrieving a CPUState pointer via env_cpu(). The CPU pointer is used
only to access the RISCVCPUConfig object and nothing else.

Let's use riscv_cpu_cfg() to access what we need directly without these
2 pointers.
