kzalloc() return should always be checked - notably in example code
where this may be seen as reference. On failure of allocation in
livepatch_fix1_dummy_alloc() respectively dummy_alloc() previous
allocation is freed (thanks to Petr Mladek <pmladek@xxxxxxxx> for
catching this) and NULL returned.

Hi Sasha,
I am not sure what stable policy is, but the patch is for samples/
directory and I do not think it is something which should necessarily go
to stable. It is your call though.
