btrfs: simplify btrfs_check_leaf_* helpers into a single helper
We have two helpers for checking leaves, because we have an extra check
for debugging in btrfs_mark_buffer_dirty(), and at that stage we may
have item data that isn't consistent yet. However we can handle this
case internally in the helper, if BTRFS_HEADER_FLAG_WRITTEN is set we
know the buffer should be internally consistent, otherwise we need to
skip checking the item data.
Simplify this helper down a single helper and handle the item data
checking logic internally to the helper.
