There are some btrfs test cases utilizing _btrfs_forget_or_module_reload() to unregister all btrfs devices. However _btrfs_forget_or_module_reload() will unregister all devices, meaning if TEST_DEV is part of a multi-device btrfs, after those test cases TEST_DEV will no longer be mountable. This patch will introduce a new function, btrfs_rescan_devices() to undo the unregister, so that all later test cases can mount TEST_DEV without any problem. Since we are here, also add a missing _require_btrfs_forget_or_module_loadable for btrfs/225.
