btrfs: check if the transaction was aborted at btrfs_wait_for_commit()

Browse source

commit bf7ecbe987 upstream.

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.
