tests: fix btrfs build error on some old systems

Fix the following build error on SLE 11 SP4:

btrfs.c: In function 'btrfs_test_dev_replace_ioctl':
btrfs.c:1570: error: unknown field 'start' specified in initializer

* tests/btrfs.c (btrfs_test_dev_replace_ioctl): Move initialization
of struct btrfs_ioctl_dev_replace_args.start.srcdevid out of the
designated initializer.
