    nvme: Bump the alignment of struct nvme_health_information_page to 8
    
    This ensures that embedded uint64_t values used for statistics
    counters are aligned when allocating a structure on the stack or as
    part of a containing structure.  In particular this quiets
    -Waddress-of-packed-member warnings from GCC when compiling the code
    in nvmfd to update the stats.
    
    Reported by:    GCC
