cuse: fix fuse_conn_kill()
fuse_conn_kill() removed fc->entry, called fuse_ctl_remove_conn() and fuse_bdi_destroy(). None of which is appropriate for cuse cleanup. The fuse_ctl_remove_conn() decrements the nlink on the control filesystem, which is totally bogus. The others are harmless but unnecessary. So move these out from fuse_conn_kill() to fuse_put_super() where they belong. Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>
