perf kwork: Add `kwork` and `src_type` to work_init() for 'struct kwork_class'

To support different types of reports, two parameters `struct perf_kwork
* kwork` and `enum kwork_trace_type src_type` are added to work_init()
of struct kwork_class for initialization in different scenarios.

No functional change intended.
