cpufreq: scpi: Fix null-ptr-deref in scpi_cpufreq_get_rate()
[ Upstream commit 73b24dc731731edf762f9454552cb3a5b7224949 ]
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.
Fixes: 343a8d17fa8d ("cpufreq: scpi: remove arm_big_little dependency")
