[Samba] Testparm with two arguments in 3.0.0rc3

[Jay Fenlason]

What should testparm do if you provide only two arguments to it (a
config file and either an IP address or a hostname)?  According to the
manual page, it needs both a hostname and an IP address.  With the
3.0.0rc3 testparm, if you provide only two arguments, it ignores the
second one.  With the testparm in 2.2.7, it performed the access
testing, and possibly returned bogus results if a hostname was given,
but the access control was by IP address, or vice versa.
