dax/fsdev: fail probe on invalid pgmap offset
Convert the WARN_ON to a fatal error when pgmap_phys > phys. This
condition means the remapped region starts after the device's data
region, which is an impossible state. Previously the probe continued
with data_offset=0, leaving virt_addr silently misaligned. Now probe
returns -EINVAL with a diagnostic message.
