From: Darrick J. Wong <darrick.wong@xxxxxxxxxx>
Ensure that we propagate the bigtime inode flag correctly when creating
new inodes. There critical part here is to use the new_diflags2 field
in the incore geometry just like we do in the kernel.
We also modify xfs_flags2diflags2 to have the same behavior as the
kernel. This isn't strictly needed here, but we aim to avoid letting
userspace diverge from the kernel function when we can.
