From: Gu JinXiang <g...@cn.fujitsu.com>
patch for commit 921518924084
("btrfs: handle dynamically reappearing missing device").
Since BTRFS_DEV_STATE_IN_FS_METADATA will be clear in
btrfs_open_one_device, 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.
