cope with potentially long ->d_dname() output for shmem/hugetlb
commit 118b23022512eb2f41ce42db70dc0568d00be4ba upstream. dynamic_dname() is both too much and too little for those - the output may be well in excess of 64 bytes dynamic_dname() assumes to be enough (thanks to ashmem feeding really long names to shmem_file_setup()) and vsnprintf() is an overkill for those guys.
