[PATCH v2 07/37] GDB: testsuite: riscv: Don't return value from top-level (sed)

[Thiago Jung Bauermann <thiago.bauermann@linaro.org>]

This patch is purely the result of running:

$ sed -i 's/^    return -1/    return/' riscv*.exp*

and

$ sed -i 's/^    return 0/    return/' riscv*.exp*

inside gdb/testsuite/gdb.arch.
