Remove duplicated RX ctrl_iface hexdump

The newer wpa_dbg() print includes the same information in a more
convenient form, so remove the duplicate RX ctrl_iface hexdump in the
cases where there is no key material in the control interface commands
(the possible-key-material case is still using wpa_hexdump_ascii_key).
