reiserfs: Replace one-element array with flexible-array member

One-element arrays are deprecated, and we are replacing them with flexible
array members instead. So, replace one-element array with flexible-array
member in direntry_uarea structure, and refactor the rest of the code,
accordingly.

Worth mentioning is that before these changes, the original implementation
was returning two-too many bytes in function direntry_create_vi():

fs/reiserfs/item_ops.c:464:     int size = sizeof(struct direntry_uarea);
...
fs/reiserfs/item_ops.c-490-     size += (dir_u->entry_count * sizeof(short));
...
fs/reiserfs/item_ops.c-517-     return size;
