Proof step 3 from proof crash-neutral-move-buf (previous step)

# lpt = # avol, awbuf-inv(avol, bleb), synced(avol0), avol0 ↓ avol, bleb = buffered(m) ∨ (bleb = nobuffer ∨ is-aligned(# avol[bleb.leb].data, EB_PAGE_SIZE)) ∧ m < # avol ∧ avol[m].mapped? ∧ m0 = # avol[m].data ⊦ ⟨awbuf_move_buf#(m, m0, adr0, m2, nx0, avol, lpt, ns0, isbuf; bleb; err)⟩ true
