btrfs: fix rw_devices miss match after seed replace
reproducer:
reproducer:
mount /dev/sdb /btrfs
btrfs dev add /dev/sdc /btrfs
btrfs rep start -B /dev/sdb /dev/sdd /btrfs
umount /btrfs
WARNING: CPU: 0 PID: 3882 at fs/btrfs/volumes.c:892 __btrfs_close_devices+0x1c8/0x200 [btrfs]()
which is
WARN_ON(fs_devices->rw_devices);
The problem here is that we did not add one to the rw_devices when
we replace the seed device with a writable device.
