LU-2462 e2fsprogs Consider DIRENT_LUFID flag in link_proc().

While adding the new file entry in directory block, link_proc()
calculates minimum record length of the existing directory entry
without considering the dirent data size and which leads to
corruption. Changed the code to use EXT2_DIR_REC_LEN() which will
return correct record length including dirent data size.
