btrfs: fix warnings after changes in btrfs_abort_transaction

fs/btrfs/volumes.c: In function ‘btrfs_create_uuid_tree’:
fs/btrfs/volumes.c:3909:3: warning: format ‘%d’ expects argument of type ‘int’, but argument 4 has type ‘long int’ [-Wformat=]

fs/btrfs/ioctl.c: In function ‘create_subvol’:
fs/btrfs/ioctl.c:549:3: warning: format ‘%d’ expects argument of type ‘int’, but argument 4 has type ‘long int’ [-Wformat=]
   btrfs_abort_transaction(trans, root, PTR_ERR(new_root));

PTR_ERR returns long, but we're really using 'int' for the error codes
everywhere so just set and use the local variable.
