Filipe Manana d9e846072f btrfs: fix bitmap leak when loading free space cache on duplicate entry 
[ Upstream commit 320d8dc612 ]

If we failed to link a free space entry because there's already a
conflicting entry for the same offset, we free the free space entry but
we don't free the associated bitmap that we had just allocated before.
Fix that by freeing the bitmap before freeing the entry.
