RISC-V: Fix missing initialization of riscv_csr_extra structs
The next pointer of struct riscv_csr_extra was not always initilized to NULL or a valid pointer, causing the assembler to attempt to read through an uninitialized pointer on startup. gas/ChangeLog: * config/tc-riscv.c (riscv_init_csr_hash): NULL initilize next pointer when creating struct riscv_csr_extra.
