lib: cpus: sanity check pointers before use

The cpu_ops structure contains a lot of function pointers. It
is a good idea to verify that the function pointer is not NULL
before executing it.

This patch sanity checks each pointer before use to prevent any
unforeseen crashes. These checks have been enabled for debug
builds only.
