fs/ext4: Only change S_DAX on inode load
To prevent complications with in memory inodes we only set S_DAX on
inode load. FS_XFLAG_DAX can be changed at any time and S_DAX will
change after inode eviction and reload.
Add init bool to ext4_set_inode_flags() to indicate if the inode is
being newly initialized.
Assert that S_DAX is not set on an inode which is just being loaded.
