Xu Kuohai 54bfc9ef60 riscv, bpf: Fix incorrect runtime stats 
[ Upstream commit 10541b374a ]

When __bpf_prog_enter() returns zero, the s1 register is not set to zero,
resulting in incorrect runtime stats. Fix it by setting s1 immediately upon
the return of __bpf_prog_enter().

Fixes: 49b5e77ae3 ("riscv, bpf: Add bpf trampoline support for RV64")
