[obv][commit] Eliminate a single-use variable in eval.c

[Siddhesh Poyarekar <siddhesh@redhat.com>]

Hi,

I have committed another small change that eliminates a local
variable that is used only once in the function with the direct function
call.  This is an attempt to make the changes for 64-bit struct offset
and length smaller.  For a context on those changes, please refer:
