[PATCH 01/30] btrfs: Add missing annotation for release_extent_buffer()

[Jules Irenge]

Sparse reports a warning at release_extent_buffer()
warning: context imbalance in release_extent_buffer() - unexpected unlock

The root cause is the missing annotation at release_extent_buffer()
Add the missing __releases(&eb->refs_lock) annotation
