Subject: [PATCH] fs/dax: remove unused function

When CONFIG_FS_DAX is enabled we get this warning:
fs/dax.c:106:14: warning: ‘dax_make_page_entry’ defined but not used
   [-Wunused-function]
 static void *dax_make_page_entry(struct page *page, void *entry)
              ^~~~~~~~~~~~~~~~~~~
Remove the unused function.

Fixes: 9bfcbe5ef12f ("dax: Convert dax_lock_page to XArray")
