Btrfs: do not mark the chunk as readonly if in degraded mode
If a RAID setup has chunks that span multiple disks, and one of those
disks has failed, btrfs_chunk_readonly will return 1 since one of the
disks in that chunk's stripes is dead and therefore not writeable. So
instead if we are in degraded mode, return 0 so we can go ahead and
allocate stuff. Without this patch all of the block groups in a RAID1
setup will end up read-only, which will mean we can't add new disks to
the array since we won't be able to make allocations.
