fuse: add list of writable files to fuse_inode
Each WRITE request must carry a valid file descriptor. When a page is written back from a memory mapping, the file through which the page was dirtied is not available, so a new mechananism is needed to find a suitable file in ->writepage(s). A list of fuse_files is added to fuse_inode. The file is removed from the list in fuse_release(). This patch is in preparation for writable mmap support.
