[PATCH 3.16 078/366] ext4: correct endianness conversion in __xattr_check_inode()

From: Eric Biggers <ebiggers@google.com>

commit 199625098a18a5522b424dea9b122b254c022fc5 upstream.

It should be cpu_to_le32(), not le32_to_cpu(). No change in behavior.

Found with sparse, and this was the only endianness warning in fs/ext4/.
