[PATCH] xfs/440: skip test if the dax mount option is enabled

[Xiao Yang <yangx.jy@fujitsu.com>]

With the enabled dax mount option, this test doesn't
work well because unwritten extents will not be allocated
according to the CoW extent size hint.

Try to fix the following error by the patch:
$./check xfs/440
    ...
     fsgqa 64 0 0
     Reflink and CoW
     root 0 0 0
    -fsgqa 1152 0 0
    +fsgqa 128 0 0
     Sync
     root 0 0 0
    ...
