bcachefs: Fix build errors with gcc 10
gcc 10 seems to complain about array bounds in situations where gcc 11
does not - curious.
This unfortunately requires adding some casts for now; we may
investigate getting rid of our __u64 _data[] VLA in a future patch so
that our start[0] members can be VLAs.
