[PATCH] Remove scanbuild warning in hypertransport.c

[Myles Watson]

Scanbuild finds a possible null pointer dereference here:

http://www.coreboot.org/~stepan/coreboot-scanbuild/kontron_986lcd-m-scanbuil...

There are two ways that I thought of fixing it.

The first way is just to insert an

if (first == NULL) return NULL;

at line 53 and remove the if (first) condition.

The only problem with that is that it makes the change look bigger than it is.

Here's a simpler looking change.  Either one is fine with me.  Boot
tested on s2892.
