cpufreq: governor: Free dbs_data directly when gov->init() fails

[ Upstream commit 916f13884042f615cfbfc0b42cc68dadee826f2a ]

Due to the kobject embedded in the dbs_data doest not has a release()
method yet, it needs to use kfree() to free dbs_data directly when
governor fails to allocate the tunner field of dbs_data.
