[PATCH 7/7] nvme: Send change uevent when AEN completes

[Zou Ming]

Hi Keith:
   Thanks,Send All AEN info to user space looks good to me.

   In addition I have a question, is there a scene where repeated asynchronous events are received?
   Because the event is sent to the user space for asynchronous processing, and at the same time issued a new asynchronous event request command.
   The user space may be processed slower than the issued command, resulting in a duplicate asynchronous event report.

Best regards,
Zou Ming.
