Subject: [PATCH] IB/hfi1: make hist static

From: chongjiapeng <jiapeng.chong@...ux.alibaba.com>

This symbol is not used outside of trace.c, so marks it static.

Fix the following sparse warning:

drivers/infiniband/hw/hfi1/trace.c:491:23: warning: symbol 'hist' was
not declared. Should it be static?
