EDAC: Use edac_debugfs_remove_recursive() in edac_debugfs_exit()

debugfs_remove() is used to remove a file or a directory from the
debugfs filesystem on an EDAC device exit. However edac_debugfs might
not be empty. This is similar to

30f84a891bf6 ("EDAC: Use edac_debugfs_remove_recursive()")

which changed the EDAC MCI code to use edac_debugfs_remove_recursive().
