Squashfs: Ensure all readahead pages have been used
In the recent work to remove page->index, a sanity check
that ensured all the readhead pages were covered by the
Squashfs data block was removed [1].
To avoid any regression, this commit adds the sanity check
back in an equivalent way. Namely the page actor will now
return error if any pages are unused after completion.
