The frequency list buffer was already validated in
power_acpi_cpufreq_freqs(), so the newly added check was redundant.
To keep consistency with power_pstate_cpufreq_freqs(), remove the
original check and update the log message.
Fixes: 2e6ccdb4e088 ("power: fix frequency list to handle null buffer")
