[PATCH 1/1] riscv: fix building with CONFIG_SPL_SMP=n

[Heinrich Schuchardt]

Building with CONFIG_SPL_SMP=n results in:

arch/riscv/lib/spl.c: In function ‘jump_to_image_no_args’:
arch/riscv/lib/spl.c:33:6:
error: unused variable ‘ret’ [-Werror=unused-variable]
   33 |  int ret;
      |      ^~~

Define the variable ret as __maybe_unused.

Fixes: 191636e44898 ("riscv: Introduce SPL_SMP Kconfig option for U-Boot
SPL")
Fixes: 8c59f2023cc8 ("riscv: add SPL support")
