linux-3.10.y commit bf00d124e07 (Btrfs: add missing brelse when superblock checksum fails) was misapplied to a later error handling site. The result is that it doesn't actually free the buffer on checksum failure but does attempt to double free the buffer if unsupported features are used.
The backport of b2acdddfad1 in other branches is correct.
