fuse: fix writepages on 32bit
commit 9de5be06d0a89ca97b5ab902694d42dfd2bb77d2 upstream.
Writepage requests were cropped to i_size & 0xffffffff, which meant that
mmaped writes to any file larger than 4G might be silently discarded.
Fix by storing the file size in a properly sized variable (loff_t instead
of size_t).
