Nicholas Mc Guire 086ed19ecf livepatch: check kzalloc return values 
[ Upstream commit 5f30b2e823484ce6a79f2b59901b6351c15effa6 ]

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@suse.com> for
catching this) and NULL returned.
