Fix memory write operation in RV32A

The current implementation incorrectly writes only half word instead of
the entire word when storing computation results back to memory in A
extension instructions. Fix this issue by replacing the usage of
mem_write_s() function with mem_write_w() function, ensuring that the
entire word is properly written to memory.
