Josef Bacik 2cdc342c20 Btrfs: fix bitmap regression
In cleaning up the clustering code I accidently introduced a regression by
adding bitmap entries to the cluster rb tree.  The problem is if we've maxed out
the number of bitmaps we can have for the block group we can only add free space
to the bitmaps, but since the bitmap is on the cluster we can't find it and we
try to create another one.  This would result in a panic because the total
bitmaps was bigger than the max bitmaps that were allowed.  This patch fixes
this by checking to see if we have a cluster, and then looking at the cluster rb
tree to see if it has a bitmap entry and if it does and that space belongs to
that bitmap, go ahead and add it to that bitmap.

I could hit this panic every time with an fs_mark test within a couple of
minutes.  With this patch I no longer hit the panic and fs_mark goes to
completion.  Thanks,
