btrfs: use the super_block as holder when mounting file systems

Browse source

The file system type is not a very useful holder as it doesn't allow us
to go back to the actual file system instance.  Pass the super_block
instead which is useful when passed back to the file system driver.

This matches what is done for all other block device based file systems,
and allows us to remove btrfs_fs_info::bdev_holder completely.
