ipv6: do not check fib6_has_expires() in fib6_info_release()
My prior patch went a bit too far, because apparently fib6_has_expires()
could be true while f6i->gc_link is not hashed yet.
fib6_set_expires_locked() can indeed set RTF_EXPIRES
while f6i->fib6_table is NULL.
Original syzbot reports were about corruptions caused
by dangling f6i->gc_link.
Fixes: 5a08d0065a91 ("ipv6: add debug checks in fib6_info_release()")
