Subject: ARM: cpuidle: Fix error return code

From: Christophe Jaillet <redacted>

commit af48d7bc3756a0cd882d65bff14ab39746ba57fe 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.
