[PATCH] csky: kprobe: fix unreachable code in simulate_blz32

From: Menglong Dong The type of 'val' is 'unsigned long' in simulate_blz32, so 'val < 0' can't be true. When 'csky_insn_reg_get_val' fails, 'false' will be returned. We can directly use its return value here. Fixes: 33e53ae1ce41 ("csky: Add kprobes supported") Signed-off-by: Menglong Dong ---
