[PATCH] riscv: fix minor typo in syscall.h comment

[Austin Kim]

From: Austin Kim <austin.kim@lge.com>

Some developers may be confused because RISC-V does not have
a register named r0. Also, orig_r0 is not available in pt_regs structure,
which is specific to riscv. So we had better fix this minor typo.
