cpufreq: loongson2: Unregister platform_driver on failure
When cpufreq_register_driver() returns error, the cpufreq_init() returns
without unregister platform_driver, fix by add missing
platform_driver_unregister() when cpufreq_register_driver() failed.
Fixes: f8ede0f700f5 ("MIPS: Loongson 2F: Add CPU frequency scaling support")
