riscv: extable: make fixup_exception() return bool
The return values of fixup_exception() and riscv_bpf_fixup_exception() represent a boolean condition rather than an error code, so it's better to return `bool` rather than `int`. Signed-off-by: Jisheng Zhang <jszhang@kernel.org> Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
