[AX.25]: Fix default address and broadcast address initialization.

Only the callsign but not the SSID part of an AX.25 address is ASCII
based but Linux by initializes the SSID which should be just a 4-bit
number from ASCII anyway.

Fix that and convert the code to use a shared constant for both default
addresses.  While at it, use the same style for null_ax25_address also.
