cpufreq/amd-pstate: Return -ENOMEM on failure to allocate profile_name

Browse Source 
Failure to allocate profile name will return -EINVAL from
platform_profile_register() while in fact, it is a failure to allocate
memory for the profile_name string.

Return -ENOMEM when kasprintf() fails to allocate profile_name string.
