[PATCH 1/2] nvme: define the SMART / Health Status async event bit

[Guixin Liu <kanie@linux.alibaba.com>]

NVMe 2.x requires controllers to support the SMART / Health Status
asynchronous event (OAES bit 1), but the only event bits the header
defines are namespace attribute, firmware activation, ANA change and
discovery change. Define the missing bit so the host can subscribe to
the event.
