Wang Yugui 1822b12564 btrfs-progs: receive: fix a segfault when passing error pointer to free() 
I noticed a segfault of 'btrfs receive'.

  $ gdb
   #0  process_clone (path=0x23829d0 "after.s1.txt", offset=0, len=2097152, clone_uuid=<optimized out>,
      clone_ctransid=<optimized out>, clone_path=0x2382920 "after.s1.txt", clone_offset=0, user=0x7ffe21985ba0)
      at cmds/receive.c:793
  793                     free(si->path);
  (gdb) p si
  $1 = (struct subvol_info *) 0xfffffffffffffffe

'si' was an error pointer value. Add the check to make sure we don't
pass such pointer to free().
