fsverity: replace fsverity_hash_page() with fsverity_hash_block()
In preparation for allowing the Merkle tree block size to differ from
PAGE_SIZE, replace fsverity_hash_page() with fsverity_hash_block(). The
new function is similar to the old one, but it operates on the block at
the given offset in the page instead of on the full page.
(For now, all callers still pass a full page.)
