Hangyu Hua ce5a6df21a fuse: dax: set fc->dax to NULL in fuse_dax_conn_free()

commit 7f8ed28d1401320bcb02dda81b3c23ab2dc5a6d8 upstream.

fuse_dax_conn_free() will be called when fuse_fill_super_common() fails
after fuse_dax_conn_alloc(). Then deactivate_locked_super() in
virtio_fs_get_tree() will call virtio_kill_sb() to release the discarded
superblock. This will call fuse_dax_conn_free() again in fuse_conn_put(),
resulting in a possible double free.

Fixes: 1dd539577c42 ("virtiofs: add a mount option to enable dax")
