xfs/libxfs: replace kmalloc() and memcpy() with kmemdup()

The source static analysis tool gave the following advice:

./fs/xfs/libxfs/xfs_dir2.c:382:15-22: WARNING opportunity for kmemdup

 → 382         args->value = kmalloc(len,
   383                          GFP_KERNEL | __GFP_NOLOCKDEP | __GFP_RETRY_MAYFAIL);
   384         if (!args->value)
   385                 return -ENOMEM;
   386
 → 387         memcpy(args->value, name, len);
   388         args->valuelen = len;
   389         return -EEXIST;

Replacing kmalloc() + memcpy() with kmemdump() doesn't change semantics.
Original code works without fault, so this is not a bug fix but proposed improvement.
