!4647 hisi_ptt: Move type check to the beginning of hisi_ptt_pmu_event_init()

Merge Pull Request from: @lujunhuaHW 
 
When perf_init_event() calls perf_try_init_event() to init pmu driver,
searches for the next pmu driver only when the return value is -ENOENT.
Therefore, hisi_ptt_pmu_event_init() needs to check the type at the
beginning of the function.
Otherwise, in the case of perf-task mode, perf_try_init_event() returns
-EOPNOTSUPP and skips subsequent pmu drivers, causes perf_init_event() to
fail.
