Su Yue 72eb9fc82a btrfs: tree-checker: check if chunk item end overflows 
[ Upstream commit 347fb0cfc9 ]

While mounting a crafted image provided by user, kernel panics due to
the invalid chunk item whose end is less than start.

  [67.558449] PKRU: 55555554
  [67.581146] note: mount[613] exited with preempt_count 2

The image has a chunk item which has a logical start 37748736 and length
18446744073701163008 (-8M). The calculated end 29360127 overflows.
EEXIST was caught by insert_state() because of the duplicate end and
extent_io_tree_panic() was called.

Add overflow check of chunk item end to tree checker so it can be
detected early at mount time.
