[0/2] Two DAX fixes for 4.20

Message

These both fix race conditions in dax_lock_mapping_entry().  I've tagged
them both for 4.19 backport, which will fail and I'll do the equivalent
patch for it.  Dan, do you want to take these through your tree?

  dax: Check page->mapping isn't NULL
  dax: Don't access a freed inode
