dax: add tracepoints to dax_pmd_load_hole()
Add tracepoints to dax_pmd_load_hole(), following the same logging
conventions as the tracepoints in dax_iomap_pmd_fault().
Here is an example PMD fault showing the new tracepoints:
read_big-1478 [004] .... 238.242188: xfs_filemap_pmd_fault: dev 259:0 ino 0x1003
