fuse: move initialization of fuse_file to fuse_writepages() instead of in callback
Prior to this change, data->ff is checked and if not initialized then
initialized in the fuse_writepages_fill() callback, which gets called
for every dirty page in the address space mapping.
This logic is better placed in the main fuse_writepages() caller where
data.ff is initialized before walking the dirty pages.
No functional changes added.
