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)
Some momory will be left in offline state when calling offline_memory_expect_fail() failed. Restore it before exit.

Correct test's name for mem-on-off-test.sh/cpu-on-off-test.sh.
