btrfs: Remove block_rsv parameter from btrfs_drop_snapshot
It's no longer used following 30d40577e322 ("btrfs: reloc: Also queue orphan reloc tree for cleanup to avoid BUG_ON()"), so just remove it. Signed-off-by: Nikolay Borisov <nborisov@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
