nvme: trace all async notice events
This patch removes the tracing of the NVMe Async events out of the switch so that it can trace all the events including the ones which are not handled in the nvme_handle_aen_notice(). The events which are not handled in the nvme_handle_aen_notice() such as NVME_AER_NOTICE_DISC_CHANGED corresponding event identifier needs to be added in the drivers/nvme/host/trace.h so that it can stringify the AER .
