Kernel panic happens after mount and ls specific btrfs image
Way to reproduce:
1. download and unpack btrfs image from tar(sparse file)(tar -Sxf img.tar)
2. mount btrfs (sudo mount -t btrfs -o rw,noatime,compress=no,commit=5 71bb49cf-26f1-484a-832c-e966f43adca9.img broken)
3. list files in mount point (ls -al broken)
the system down to kernel panic with log above
(looks like 3.19.x and 4.2.x not affected, only 4.4.x)
