Sometimes dm_swap_table couldn't be used in time.
For example, during the origin construction of
dm-snapshot, the sys_ioctl table_load will try to
detect the lower device origin-real whether support
direct access or not. But origin-real md's struct
dm-table pointer has not

Changes
v1->v2:
Add NULL funtions for origin_dax_direct_access and
origin_dax_copy_from/to_iter in order to avoid building
error when CONFIG_DAX_DRIVER has NOT been enabled.

Reconstruct origin_dax_direct_access and expand functions
origin_dax_copy_to/from_iter for DAX operations of dm-snapshot.
Here is the call trace of origin_dax_copy_to_iter,
origin_dax_copy_to_iter will callin dm-linear (-real) for further
dax_operation.

This series patches are used to realize the dax_operations for dm-snapshot
with persistent memory device.
Here are the steps about how to verify the function.
1. Configure the persistent memory to fs-dax mode and create namespace with
ndctl;
2. find them in /dev;
# ndctl
