s390: chp: handle CRW_ERC_INIT for channel-path status change
When channel path is identified as the report source code (RSC) of a CRW, and initialized (CRW_ERC_INIT) is recognized as the error recovery code (ERC) by the channel subsystem, it indicates a "path has come" event. Let's handle this case in chp_process_crw().
