Cong Wang d5c7c745f2 net/wan: fix a double free in x25_asy_open_tty() 
When x25_asy_open() fails, it already cleans up by itself,
so its caller doesn't need to free the memory again.

It seems we still have to call x25_asy_free() to clear the SLF_INUSE
bit, so just set these pointers to NULL after kfree().

Fixes: 3b780bed31 ("x25_asy: Free x25_asy on x25_asy_open() failure.")
