cpuidle: fix improper return value on error
In function cpuidle_add_state_sysfs(), variable ret takes the return
value. Its value should be negative on errors. Because ret is reset in
the loop, its value will be 0 during the second and after repeat of the
loop. If kzalloc() returns a NULL pointer then, it will return 0. It may
be better to explicitly assign "-ENOMEM" when the call to kzalloc()
fails.
