Bugfix for interface.c

[Kai Fritzowsky]

Hi!

After applying several patches to a Solaris 7 box, the nmbd died right after
startup.
I tracked the bug down to a memcmp() call in source/lib/interface.c.
Obviously the call relies on the fact that the compared structures consist
of one single memory block, which is not true for the patched Solaris 7
libc any more.

My system:
# uname -svr
SunOS 5.7 Generic_106541-12
# nmbd -V
Version 2.0.7

The bugfix for the described problem is attached.

Greetings,
