Henry Martin 28fbd7b13b cpufreq: scpi: Fix null-ptr-deref in scpi_cpufreq_get_rate() ...

[ Upstream commit 73b24dc731 ]

cpufreq_cpu_get_raw() can return NULL when the target CPU is not present
in the policy->cpus mask. scpi_cpufreq_get_rate() does not check for
this case, which results in a NULL pointer dereference.
