riscv: signal: fix some warnings reported by sparse

Browse Source 
Clean up a few warnings reported by sparse in
arch/riscv/kernel/signal.c.  These come from code that was added
recently; they were missed when I initially reviewed the patch.

Fixes: 818d78ba1b ("riscv: signal: abstract header saving for setup_sigcontext")
