riscv: implement a memset like function for text
The BPF JIT needs to write invalid instructions to RX regions of memory to
invalidate removed BPF programs. This needs a function like memset() that
can work with RX memory.
Implement patch_text_set_nosync() which is similar to text_poke_set() of
x86.
