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.
