cpufreq: ondemand: kernel NULL pointer dereference at dbs_check_cpu

Function dbs_check_cpu  calls __cpufreq_driver_getavg
With  policy as IN/OUT parameter.
There is possiblity of policy becoming NULL in
 __cpufreq_driver_getavg. Same policy is getting
accessed in the for loop which leads to NULL pointer dereference.
So NULL check is required for the policy
