Noticed under Ubuntu kernel builds, there were two instances where
printf() was not called with a "%s" and instread directly printed
the string. This can potentially result in a crash and is considered
bad form by gcc. It has been fixed by adding the needed "%s".
This check is part of ztest and a memory failure here is unlikely.
However, if this does occur simply exiting is an perfectly valid
way to handle the issue and it resulves the compiler warning.
ztest.c:5522: error: ignoring return value of 'asprintf',
declared with attribute warn_unused_result
Under FC11 rpm builds by default add the --fortify-source option which
ensures that functions flagged with certain attributes must have their
return codes checked. Normally this is just a warning but we always
build with -Werror so this is fatal. Simply wrap the function in a
verify call to ensure we catch a failure if there is one.
