fuse: write inode in fuse_vma_close() instead of fuse_release()
Fuse ->release() is otherwise asynchronous for the reason that it can
happen in contexts unrelated to close/munmap.
Inode is already written back from fuse_flush(). Add it to
fuse_vma_close() as well to make sure inode dirtying from mmaps also get
written out before the file is released.
Also add error handling.
