A use after free vulnerability was found in prepare_to_relocate in
fs/btrfs/relocation.c in btrfs in the Linux Kernel. This possible flaw can be
triggered by calling btrfs_ioctl_balance() before calling btrfs_ioctl_defrag().

Clean cherry picks.

Compile and smoke tested.

[Potential Regression]
Expect relatively low regression.
