connectd: fix bad assert.

This code was trying to check that the address type is not one of the ADDR_TYPE_TOR*
types, but the is_toraddr() function checks a domain name!  The cast should have been
a clue that this was wrong!

Anyway, wireaddr_to_addrinfo() aborts on these cases already, so the asserts here are
superfluous.

Found in unrelated CI run:
