A bug was triggered while using seed device:
# mkfs.btrfs /dev/loop1
# btrfstune -S 1 /dev/loop1
# mount -o /dev/loop1 /mnt
# btrfs dev add /dev/loop2 /mnt
btrfs: block rsv returned -28

Since seed device is readonly, there's no usable space in the filesystem.
Afterwards we add a sprout device to it, and the kernel creates a METADATA
block group and a SYSTEM block group where comes free space we can reserve,
but we still get revervation failure because the global block_rsv hasn't
been updated accordingly.
