Matthew Wilcox (Oracle) 33e53f2cac btrfs: fix potential overflow in cluster_pages_for_defrag on 32bit arch 
commit a1fbc6750e212c5675a4e48d7f51d44607eb8756 upstream.

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: df480633b891 ("btrfs: extent-tree: Switch to new delalloc space reserve and release")
