ARM: cpuidle: Fix error return code

Browse Source 
commit af48d7bc37 upstream.

We know that 'ret = 0' because it has been tested a few lines above.
So, if 'kzalloc' fails, 0 will be returned instead of an error code.
Return -ENOMEM instead.

Fixes: a0d46a3dfd ("ARM: cpuidle: Register per cpuidle device")
