dax: use READ_ONCE() in dax_holder()
A future fuse patch will utilize dax_holder() in RCU context to make sure
that the holder can't be freed by a racing fs_put_dax.
This patch just makes sure that dax_holder() works properly in such a
context by adding READ_ONCE() (equivalent to rcu_dereference minus sanity
checks).
Fixing XFS is out of scope for this patchset.
