Subject: [PATCH] btrfs: check if the transaction was aborted at
 btrfs_wait_for_commit()

At btrfs_wait_for_commit() we wait for a transaction to finish and then
always return 0 (success) without checking if it was aborted, in which
case the transaction didn't happen due to some critical error. Fix this
by checking if the transaction was aborted.
