[PATCH] ext4: set awu_max_opt to awu_max

[Pankaj Raghav <p.raghav@samsung.com>]

commit 5d894321c49e ("fs: add atomic write unit max opt to statx")
added atomic write max optimal to statx. As XFS can support large atomic
writes through SW, max_opt exposes the value that will be HW accelerated
atomics.

As ext4 does not support SW atomics, set awu_max_opt to awu_max.
