i8k: Fix non-SMP operation
commit 6d827fbcc370ca259a2905309f64161ab7b10596 upstream.
Commit f36fdb9f0266 (i8k: Force SMM to run on CPU 0) adds support
for multi-core CPUs to the driver. Unfortunately, that causes it
to fail loading if compiled without SMP support, at least on
32 bit kernels. Kernel log shows "i8k: unable to get SMM Dell
signature", and function i8k_smm is found to return -EINVAL.
Testing revealed that the culprit is the missing return value check
of set_cpus_allowed_ptr.
Fixes: f36fdb9f0266 (i8k: Force SMM to run on CPU 0)
