Btrfs: fix block_rsv and space_info lock ordering
may_commit_transaction() calls
spin_lock(&space_info->lock);
spin_lock(&delayed_rsv->lock);
and update_global_block_rsv() calls
spin_lock(&block_rsv->lock);
spin_lock(&sinfo->lock);
Lockdep complains about this at run time.
Everywhere except in update_global_block_rsv(), the space_info lock is
the outer lock, therefore the locking order in update_global_block_rsv()
is changed.
