Inline_data is mutually exclusive to DAX inode flag so enabling both
of them is not expected and triggers some errors. It's a regression
test for kernel patch:
commit aa2f77920b74 ("ext4: disallow modifying DAX inode flag if inline_data has been set")
Signed-off-by: Xiao Yang <yangx.jy@xxxxxxxxxxxxxx>

V1->V2:
1) Add commit id for kernel patch.
2) Rebase on the lastest xfstests-dev.
