bcachefs: Check for writing superblocks with nonsense member seq fields

Browse source

We're seeing some unmountable filesystems due to split brain detection
going awry; it seems we somehow wrote out superblocks where we updated
the superblock seq without updating any member seq fields.

A given device's superblock should always have the main seq equal to
it's member seq field, so this is easy to check for.
