Revert "fuse: move initialization of fuse_file to fuse_writepages() instead of in callback"

This reverts commit 672c3b7457fcee9656c36a29a4b21ec4a652433e.

fuse_writepages() might be called with no dirty pages after all writable
opens were closed.  In this case __fuse_write_file_get() will return NULL
which will trigger the WARNING.

The exact conditions under which this is triggered is unclear and syzbot
didn't find a reproducer yet.
