Proof step 8 from proof refine-get-leb-size (previous step)

PEB_SIZE = n1 + 2 * m, m = EB_PAGE_SIZE, abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs), 2 * m ≤ PEB_SIZE, PEB_SIZE ≥ 2 * m ⊦ ⟨aubi_io_get_leb_size#(apebs; ; n0)⟩ (n1 = n0)

And obtained the following new goals

Proof step 9:
abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs), 2 * EB_PAGE_SIZE ≤ PEB_SIZE ⊦ ⟨aubi_io_get_leb_size#(apebs; ; n0)⟩ (LEB_SIZE = n0)
