From: Josef Bacik <josef@xxxxxxxxxxxxxx> commit fb686c6824dd6294ca772b92424b8fba666e7d00 upstream. There are a few places where we don't check the return value of btrfs_commit_transaction in relocation.c. Thankfully all these places have straightforward error handling, so simply change all of the sites at once.
