cebaf7434b4af059caca053ee1ec7ed8df91c2a7 target/riscv: use riscv_csrr in riscv_csr_read
Commit 38c83e8d3a33 ("target/riscv: raise an exception when CSRRS/CSRRC
writes a read-only CSR") changed the behavior of riscv_csrrw, which
would formerly be treated as read-only if the write mask were set to 0.
Fixes an exception being raised when accessing read-only vector CSRs
like vtype.
