Xin Yin 9e6474e5d7 erofs: fix fsdax unavailability for chunk-based regular files 
[ Upstream commit 18bddc5b67 ]

DAX can be used to share page cache between VMs, reducing guest memory
overhead. And chunk based data format is widely used for VM and
container image. So enable dax support for it, make erofs better used
for VM scenarios.

Fixes: c5aa903a59 ("erofs: support reading chunk-based uncompressed files")
