Btrfs: fix "mutually exclusive op is running" error code
The error code that is returned in response to starting a mutually exclusive operation when there is one already running got silently changed from EINVAL to EINPROGRESS by 5ac00add. Returning EINPROGRESS to, say, add_dev, when rm_dev is running is misleading. Furthermore, the operation itself may want to use EINPROGRESS for other purposes.
