riscv/barrier: Add missing space after ','

Browse Source 
The past form of RISCV_FENCE would cause checkpatch.pl to issue
error messages, the example is as follows:
ERROR: space required after that ',' (ctx:VxV)
26: FILE: arch/riscv/include/asm/barrier.h:27:
+#define __smp_mb()         RISCV_FENCE(rw,rw)
                                          ^
fix the remaining of RISCV_FENCE.
