[PATCH] fix sparse warning in xfs_da_btree.c

[Christoph Hellwig <hch@xxxxxx>]

The first use in xfs_da_node_lookup_int would have to be __be32.
But we can just remove this temporary variable use completely and
make sparse happy.  The variable is used later in the function for
a native endian variable so we'll have to keep it.
