The xattr code often wants to access the data pointer for blocks in an
xattr bucket. This is usually found by dereferencing the bh array
hanging off of the ocfs2_xattr_bucket structure. Rather than do this
all the time, let's provide a nice little macro. The idea is ripped
from the ocfs2_path code.
