Subject: [PATCH 4.9 082/101] btrfs: tree-checker: Fix misleading group system information

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Shaokun Zhang <zhangshaokun@...ilicon.com>

commit 761333f2f50ccc887aa9957ae829300262c0d15b upstream.

block_group_err shows the group system as a decimal value with a '0x'
prefix, which is somewhat misleading.

Fix it to print hexadecimal, as was intended.
