Matthew Wilcox (Oracle) a1fbc6750e btrfs: fix potential overflow in cluster_pages_for_defrag on 32bit arch 
On 32-bit systems, this shift will overflow for files larger than 4GB as
start_index is unsigned long while the calls to btrfs_delalloc_*_space
expect u64.

CC: stable@vger.kernel.org # 4.4+
Fixes: df480633b8 ("btrfs: extent-tree: Switch to new delalloc space reserve and release")
