refperf: Avoid null pointer dereference when buf fails to allocate



Currently in the unlikely event that buf fails to be allocated it
is dereferenced a few times.  Use the errexit flag to determine if
buf should be written to to avoid the null pointer dereferences.

Addresses-Coverity: ("Dereference after null check")
Fixes: f518f154 ("refperf: Dynamically allocate experiment-summary output buffer")
