[PATCH] tracing/eprobe: Replace kzalloc with kmalloc

From: Quanfa Fu
Date: Fri Jan 06 2023 - 22:43:49 EST


Since this memory will be filled soon below, I feel that there is
no need for a memory of all zeros here. 'snprintf' does not return
negative num according to ISO C99, so I feel that no judgment is
needed here.

No functional change intended.
