dax: add tracepoints to dax_pmd_insert_mapping()
Add tracepoints to dax_pmd_insert_mapping(), following the same logging
conventions as the tracepoints in dax_iomap_pmd_fault().
Here is an example PMD fault showing the new tracepoints:
big-1504 [001] .... 326.960743: xfs_filemap_pmd_fault: dev 259:0 ino 0x1003
