During boot scratch area is allocated based on command line
parameters or auto calculated. However, scratch area may fail
to allocate, and in that case KHO is disabled. Currently,
no warning is printed that KHO is disabled, which makes it
confusing for the end user to figure out why KHO is not
available. Add the missing warning message.
