dax/fsdev: clear vmemmap_shift when binding static pgmap
Clear pgmap->vmemmap_shift for static DAX devices. When rebinding a static
device from device_dax (which may set vmemmap_shift based on alignment) to
fsdev_dax, the stale vmemmap_shift persists on the shared pgmap. Explicitly
zero it before devm_memremap_pages() so the vmemmap is built for order-0
folios as fsdev requires.
Fixes: d5406bd458b0a ("dax: add fsdev.c driver for fs-dax on character dax")
