[PATCH master 1/7] test: self: ramfs: fix unintended macro identifier confusion

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

int ret = (_ret) is problematic, because when _ret is replaced with ret
in a macro, we end up with int ret = ret, which is valid syntactically,
but invokes undefined behavior. Guard against this by using different
identifiers.
