btrfs: Introduce extent_read_full_page_nolock()
We want this for btrfs_extent_same. Basically readpage and friends do their own extent locking but for the purposes of dedupe, we want to have both files locked down across a set of readpage operations (so that we can compare data). Introduce this variant and a flag which can be set for extent_read_full_page() to indicate that we are already locked. Partial credit for this patch goes to Gabriel de Perthuis <g2p.code@gmail.com> as I have included a fix from him to the original patch which avoids a deadlock on compressed extents.
