Merge tag 'bcachefs-2024-09-04' of git://evilpiepirate.org/bcachefs

Pull bcachefs fixes from Kent Overstreet:

 - Fix a typo in the rebalance accounting changes

 - BCH_SB_MEMBER_INVALID: small on disk format feature which will be
   needed for full erasure coding support; this is only the minimum so
   that 6.11 can handle future versions without barfing.
