Add checking for online_memory_expect_success()/
offline_memory_expect_success()/offline_memory_expect_fail(), or
the test would exit 0 although the functions return 1.

These functions return 0 if the result is as expected and 1 if the result is unexpected.

... but wouldn't we evaluate the right hand side only if the result is "0" -- expected? I might be wrong.


Wouldn't it be simpler do it as in "Online all hot-pluggable memory again"

if ! online_memory_expect_success $memory; then
	retval=1
fi

(similarly adjusting the function name)
