msm: vidc: Fix possible NULL pointer dereference 



Added NULL pointer check for platform_data structure to avoid NULL
pointer dereference error. platform_data is initialized with return 
value (driver_data) of vidc_get_drv_data() fucntion where driver_data is 
initialized with NULL pointer at the beginning.
