btrfs: refactor btrfs_free_stale_devices() to get return value
Preparatory patch to add ioctl that allows to forget a device (ie. reverse of scan). Refactors btrfs_free_stale_devices() to obtain return status. As this function can fail if it can't find the given path (returns -ENOENT) or trying to delete a mounted device (returns -EBUSY). Signed-off-by:Anand Jain <anand.jain@oracle.com> Reviewed-by:
