This patch updates btrfs/215 to work with latest upstream kernel. That's
required since commit 324bcf54c449 ("mm: use limited read-ahead to satisfy read")
changed readahead logic to always issue a read even if the RA pages are
set to 0. This results in 1 extra io being issued so the counts in the
test should be incremented by 1. Also use the opportunity to update the
commit reference since it's been merged in the upstream kernel.
