riscv: fix accessing 8-byte variable from RV32
A memory save operation to 8-byte variable in RV32 is divided into two sw instructions in the put_user macro. The current fixup returns execution flow to the second sw instead of the one after it. This patch fixes this fixup code according to the load access part.
