Richard Kennedy 270ba5f7c5 fs: re-order super_block to remove 16 bytes of padding on 64bit builds
re-order structure super_block to remove 16 bytes of alignment padding
on 64bit builds.

This shrinks the size of super_block from 712 to 696 bytes so requiring
one fewer 64 byte cache lines.

problems.
