Though v4 change log comment is right. But missed the point that
btrfs_open_one_device() clears it. My bad. Thanks for the catch.

and when alloc a new chunk in
__btrfs_alloc_chunk, device with BTRFS_DEV_STATE_IN_FS_METADATA
not be set will be skipped, so it can not alloc chunk correctly.
And from the source logic, BTRFS_DEV_STATE_IN_FS_METADATA should
be also set when reapearing a missing device.
And with this patch, xfstests-dev/tests/btrfs/154 should run
successfully.
