[PATCH v2 09/37] GDB: testsuite: s390: 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/' s390*.exp*

and

$ sed -i 's/^    return 0/    return/' s390*.exp*

inside gdb/testsuite/gdb.arch.

I didn't include changes made to return statements inside procedures.
