net/x25: fix null_x25_address handling

[ Upstream commit 06137619f061f498c2924f6543fa45b7d39f0501 ]

o x25_find_listener(): the compare for the null_x25_address was wrong.
   We have to check the x25_addr of the listener socket instead of the
   x25_addr of the incomming call.

 o x25_bind(): it was not possible to bind a socket to null_x25_address
