btrfs: unify the lock/unlock extent variants

Browse Source 
We have two variants of lock/unlock extent, one set that takes a cached
state, another that does not.  This is slightly annoying, and generally
speaking there are only a few places where we don't have a cached state.
Simplify this by making lock_extent/unlock_extent the only variant and
make it take a cached state, then convert all the callers appropriately.
