fsnotify: remove alignment padding from fsnotify_mark on 64 bit builds
Reorder struct fsnotfiy_mark to remove 8 bytes of alignment padding on 64
bit builds. Shrinks fsnotfiy_mark to 128 bytes allowing more objects per
slab in its kmem_cache and reduces the number of cachelines needed for
each structure.
